 * TitanCart Admin — Full Dashboard UI
 *
 * SOURCE FILE — THIS IS NOT A BUILD ARTIFACT.
 * This file is the hand-written, human-maintained source of the admin
 * single-page app. It is written directly against wp.element using
 * createElement() calls (no JSX), and there is no transpiler, bundler,
 * minifier, or build step anywhere in this plugin: the file in the ZIP is
 * the file the developer edits. The "build" directory name is historical
 * (the very first prototype was converted from a JSX mock-up by hand).
 * Every other JavaScript and CSS file shipped with the plugin is likewise
 * unminified source.

    /* ════════════════════════════════════════════════════════════════════
     * ORDER DOWNLOADS PANEL (S129 Phase 2)
     * ════════════════════════════════════════════════════════════════════
     * Mounted into the admin order detail page between order Items and
     * Status History. Fetches /admin/orders/{id}/downloads which returns
     * { keys, acceptances } joined to file + product info.
     *
     * Renders two sub-sections:
     *
     *   1. Issued keys — every download token created for this order's
     *      downloadable line items. Shows file name, product, status pill
     *      (active/expired/revoked), expiry, downloads/max, last activity,
     *      and a Revoke action for active keys.
     *
     *   2. Acceptances — license-agreement chargeback evidence. Shows
     *      agreement title, version, customer/email, IP/UA, accepted_at,
     *      and the truncated SHA-256 content hash. (Phase 5 starts writing
     *      these — until then, expect this section to be empty even on
     *      orders with downloadables.)
     *
     * Renders nothing when both lists are empty AFTER fetch completes —
     * orders without downloadable items don't get a noisy empty panel.

     * when unlicensed, mirroring Wishlist+).
     *
     * Three views, dispatched off the hash subId (parse() → { route, subId }):
     *   #/datafeeds              → FeedsList   (table + Add Feed)
     *   #/datafeeds/new          → FeedEditor  (create)
     *   #/datafeeds/{id}         → FeedEditor  (edit + run history + regenerate)
     *   #/datafeeds/df-settings  → FeedSettings (master toggle + global defaults)
     *
     * Each view is its own inner component that owns its own state, so the
     * parent only re-renders on a subId change — the SubscriptionsPage model,
     * which keeps typing focus stable (no inner-component remount on keystroke).

     * REST: titancart-feeds/v1, envelope { success, data, meta?, error? }.
     * GET responses key on DB column names; DECIMAL is not used here (all
     * numeric feed fields are ints) so no padded-string coercion is needed.

    /* ════════════════════════════════════════════════════════════════════
     * CART RECOVERY PAGE — Abandoned Cart Recovery admin (S228, Part 3)
     *
     * Growth → Cart Recovery. Gated into the menu by Config.abandonedCartInstalled;
     * the master enable toggle is gated by Config.abandonedCartLicenseActive.
     *
     * Four views, dispatched off the hash subId (parse() → { route, subId }):
     *   #/cartrecovery              → RecoveriesList  (tracked carts + status counts)
     *   #/cartrecovery/{id}         → RecoveryDetail  (snapshot + event timeline)
     *   #/cartrecovery/sequence     → SequenceConfig  (threshold + steps + block email builder)
     *   #/cartrecovery/cr-settings  → Settings        (master toggle + sender + guards)
     *
     * Like DataFeeds/Subscriptions, each view is its own inner component that owns
     * its own state, so keystrokes never re-render this parent (focus-safe). The
     * block builder (EmailBuilder) keeps its own draft and only PUTs on Save.
     * No JSX — h()/wp.element.createElement throughout.
     * ════════════════════════════════════════════════════════════════════ */

     * SMS NOTIFICATIONS PAGE — SMS Notifications admin (S231, Part 2)
     *
     * Growth → SMS Notifications. Gated into the menu by Config.smsNotificationsInstalled;
     * the master enable toggle is gated by Config.smsNotificationsLicenseActive.
     *
     * Four views, dispatched off the hash subId (parse() → { route, subId }):
     *   #/smsnotifications               → Overview     (stats KPIs + per-event breakdown)
     *   #/smsnotifications/log           → MessageLog   (paginated send log + filters)
     *   #/smsnotifications/subscribers   → Subscribers  (paginated opt-in registry + filter)
     *   #/smsnotifications/sms-settings  → Settings     (provider + creds + events + opt-in + test send)
     *
     * Like DataFeeds/Cart Recovery/Subscriptions, each view is its own inner component
     * that owns its own state, so keystrokes never re-render this parent (focus-safe).
     * The parent holds NO state — `tab` is derived purely from subId.
     *
     * REST namespace: titancart-sms/v1. Envelope { success, data, meta?, error? }.
     * No JSX — h()/wp.element.createElement throughout; module-scope helpers w/ ctx.

     * The page reflects three top-level states surfaced by the server:
     *
     *   - 'vendor'      → Vendor-mode bypass (titancart.io / TITANCART_VENDOR_MODE).
     *                     Single info card, no key entry.
     *   - 'licensed'    → Active marketplace key. Shows product + expiry +
     *                     activations + Refresh / Manage / Remove actions.
     *   - everything    → Subscription License entry card. POSTs the key to
     *     else            the /license endpoint — PluginPress decides which
     *                     keys are valid. (The beta access card was removed
     *                     with the beta scaffolding — KI-41, S416.)
     *
     * ⚠️ S405 (KI-40): this used to read "The trial auto-starts at plugin
     * activation (Installer::seed_trial_timestamp) so the customer is never
     * gated until trial + grace_days have elapsed." The trial is RETIRED —

                                   by the PLUGIN slug ("titancart-marketplace"). Two
                                   different identifiers for one thing, and only the
                                   marketplace server holds both — which is why it
                                   publishes the join key rather than the client
                                   guessing a second spelling of the first (KI-42).

                                   future third-party add-on — still shows Buy. The

                       ABSENCE. One Config key (`noPhoneHome`), one meaning — not

     *   whole order). Order detail surfacing vendor-scoped items, status
     *   history, customer comms is a B4+ scope (closely tied to order

     * VendorPayoutsPage (S188 + S191)
     * ════════════════════════════════
     * Storefront SPA view of the vendor's payout state — Stripe Connect
     * onboarding status + commission-split earnings YTD + commission rate.
     * Hits GET /me/vendor/payouts which bundles three reads (Stripe schema
     * view, per-line earnings aggregate via
     * VendorOrderScopeFilter::sum_completed_in_year, commission_rate
     * column).
     *
     * Why a separate route from vendor-sales:
     *   Sales is a transactional log (orders containing the vendor's
     *   products); Payouts is a settlement view (what the vendor takes home
     *   + their connection to the payout rail). Different conceptual
     *   surfaces — they answer different questions for the vendor.
     *
     * S191 surface scope (B5 commission math):
     *   The earnings tile now displays a four-way split — Your Share +
     *   Gross + Platform Cut + Commission Rate — computed inline from the
     *   B4 per-line vendor_id stamp (S190 Migration 42) via the marketplace's
     *   CommissionResolver. Pre-B4 orders are excluded by the stamp filter;
     *   the since_date footer copy surfaces that boundary cleanly so vendors
     *   understand the historical-orders gap.
     *
     *   Stripe state remains read-only — pre-B6 there's nothing to actually
     *   connect (Stripe Connect Express onboarding lands at B6).
     *
     * Layout:
     *   Row 1: Stripe Connection card (full width) — pill + helper text +
     *     disabled CTA (until B6).
     *   Row 2: Auto-fit grid (min 220px columns) — Your Share + Gross +
     *     Platform Cut + Commission Rate tiles. Stacks down to single
     *     column on narrow viewports.
     *   Row 3: Since-date boundary footer — "Calculated from completed
     *     orders since [date]" copy.
     *
     * Pattern compliance:
     *   - Pattern #109 (verify-first): /me/vendor/payouts response shape
     *     re-verified against the S191 controller docblock before this
     *     component was refactored.
     *   - Pattern #146: server emits UTC 'YYYY-MM-DD HH:MM:SS' for
     *     onboarding timestamps; 'YYYY-MM-DD' for since_date — parsed
     *     and rendered local.
     *   - Pattern #157 (mode-aware fetch): hits vendor_api_url base URL,
     *     not Config.apiUrl.
     *   - Pattern #161 (graduated S188): third SPA-mounted section.
