fix(a11y): resolve serious accessibility issues on search page (GOO-110)

- Add aria-hidden="true" to all decorative inline SVGs (bookmark, view-mode, funnel, checkmark)
- Convert save-search popover to proper dialog: role="dialog", aria-modal, focus trap, Escape key, focus return to trigger
- Add aria-pressed on list/map/split view-mode toggle buttons
- Add aria-expanded + aria-controls on mobile filter toggle button
- Add role="status" + aria-label="Đang tải..." on Suspense fallback

+ * Hosts:
+ *   - Projector base class (`application/projectors/projector.base.ts`).
+ *   - Read-model repository convention (`domain/read-repository.ts`).
+ *   - Idempotency port (`domain/projection-offset-store.ts`).
+ *   - Per-read-model kill switch (`domain/read-model-kill-switch.ts`).
+ *
+ * No projectors, repositories, or `IProjectionOffsetStore` provider are
+ * registered here yet. The Prisma-backed offset store binding lands with
+ * [GOO-187](/GOO/issues/GOO-187); per-read-model projectors land in
+ * Phase 2/3.
+ *
+ * The module is imported by `AppModule` so its DI container is wired up
+ * even while empty — keeps Phase 2/3 PRs strictly additive.
