fix: work through LOTUS_BUGS.md audit items

- ExportRoomHistory: make addEvents() async, call decryptEventIfNeeded()
  before inspecting type/content so E2EE rooms export decrypted text
- UrlPreviewCard: remove Google S2 favicon (privacy leak); show
  generic Icons.Link instead — no third-party external calls
- Profile: add statusDirtyRef so server presence sync cannot clobber
  in-flight emoji insertions or keystrokes; cleared on save/clear
- useLocalMessageSearch: include m.sticker, m.poll.start, and
  org.matrix.msc3381.poll.start in encrypted room search; index poll
  question and answer bodies
- SeasonalEffect: z-index 9997 → 9999 so overlays render above
  animated chat backgrounds
- LOTUS_BUGS.md: mark all resolved, document remaining blocked items
