- Add `#videoListTags` container to `views/explore.html` to support the hashtag helper bar in the Explore view.
- Rename `#recentVideoTags` to `#videoListTags` in `views/most-recent-videos.html` for consistency across views.
- Update `js/ui/videoListViewController.js` and `js/app.js` to reference the new generic `#videoListTags` ID.
- Update `tests/ui/video-list-view-popular-tags.test.mjs` to reflect the ID change.
This enables the hashtag aggregation and interaction features (filtering, muting, following) on the Explore tab, reusing the existing `VideoListView` logic.
- Added info buttons to Most Recent, Subscriptions, History, Channel Profile, Search, and Explore views
- Attached popovers with descriptions of feed filtration methods
- Used `attachFeedInfoPopover` helper for consistent implementation
- Verified with Playwright script (verified popover visibility and text content)
