This commit updates `HashtagPreferencesService.load` to handle transient empty responses from relays more robustly.
- It prevents `reset()` if `wasLoadedForUser` is true and the fetch returns empty, ensuring existing data isn't wiped during connectivity issues or relay switches.
- It adds a staleness check to ignore incoming events that are older than the currently loaded data, protecting against out-of-sync relays returning obsolete preferences.
This addresses the issue where hashtag interests would disappear ("turn gray") or revert to older states shortly after login when video grid filters were applied.
Prevents `HashtagPreferencesService` from aggressively resetting local state to empty when a load attempt fails due to transient issues (like empty relay lists or network errors) if valid data is already loaded for the current user. This fixes a race condition where tags would briefly load correctly and then turn gray/disappear during application initialization.
- Fix circular dependency in `js/adminListStore.js` by importing from `js/nostrClientRegistry.js`.
- Update `js/services/hashtagPreferencesService.js` to include legacy kind 30005 in filters.
- Fix JSDOM mocking in `tests/modal-accessibility.test.mjs` (navigator getter) and `UploadModal` selectors.
- Add `getRoot()` to `js/ui/components/UploadModal.js` for API consistency.
- Update `tests/magnet-utils.test.mjs` expectations to reflect removed default tracker.
- Mock `ensureActiveSignerForPubkey` in `tests/moderation/submit-report.test.mjs`.
- Fix mock loader path in `tests/moderation/trust-seeds.test.mjs` to target `trustBootstrap.js`.
- Fix duplicate pointer tags in `js/nostrEventSchemas.js`'s `buildCommentEvent`.
- Update `tests/nostr/comment-events.test.mjs` and `tests/comment-event-builder.test.mjs` to match current code behavior (legacy kinds, unique tags).
