refactor(ui): collapse Tile static class into appTile() helper

Align dashboard-tile primitive with the established helper-function +
partial convention (like tokenSelectForm / multiSelectForm). Keeps the
reusable substance (app-tile.phtml, .app-tile CSS) and makes the
primitive discoverable for modules via core/Support/helpers/ui.php.

   - **Remove button:** uses the shared `.app-icon-button` primitive + `<i class="bi bi-x-lg">` — never hand-roll a close button.
   - **Coexistence:** `multiSelectForm()` (vendor MultiSelect) remains available for small closed lists where the chip-header is acceptable. Pick `tokenSelectForm()` when the selected set can grow beyond ~10 items or typeahead is the expected interaction.
   - **Tests:** helper contract lives in `tests/Support/Helpers/TokenSelectFormHelperTest.php`; component lifecycle + entrypoint registration are enforced by `tests/Architecture/FrontendRuntime*ContractTest.php`.
+- **Dashboard tile** (icon + count + label link): use `appTile()` from `core/Support/helpers/ui.php` for dashboard / stat-grid tiles that link to a filtered list view. Renders the shared `templates/partials/app-tile.phtml` with `.app-tile` CSS. Options: `href`, `label`, `count`, `icon` (bi-*), `iconBg`, `iconColor`, `class`, `tooltip`, `tooltipPos`. Group tiles inside `<div class="app-tiles">` for the grid layout. Modules may call `appTile()` directly — no wrapper class needed.
