feat: personal room name overrides (MSC4431-style)

Browse Source 
Users can right-click any room and 'Rename for me...' to set a local
display name visible only to them. Stored in account data under
io.lotus.room_names. Shows a pencil indicator on renamed rooms.
useLocalRoomName() hook overrides useRoomName() when a local name exists.

Also includes:
- Rich room topic rendering via RoomTopicContent object (formatted_body
  support in RoomTopicViewer with HTML sanitization via sanitizeCustomHtml)
- Edit history viewer: clicking '(edited)' on a message opens a modal
  showing all prior versions with timestamps (EditHistoryModal.tsx)

### Messaging Enhancements
- **Rich room topics**: Room topics that contain formatted text (bold, links, italic) are now rendered with full HTML formatting. Falls back to plain text if no `formatted_body` is present. Activates when any room admin sets a formatted topic.
- **Edit history viewer**: Clicking the "edited" label on any edited message opens a modal showing every prior version with timestamps. Fetches all `m.replace` relations for the event and displays them oldest-to-newest. Previously the "edited" label was visible but unclickable.
- **GIF picker**: Giphy-powered GIF search and send. Button appears in the message composer only when `gifApiKey` is set in `config.json`. Sends GIF as `m.image` — fetches blob, uploads via `mx.uploadContent`, sends with `mx.sendMessage`. `FocusTrap` handles click-outside / Escape to close. When TDS is active: dark navy background (`#060c14`), orange dim border, `// GIF_SEARCH` header, CSS overrides for Giphy SDK search bar (dark bg, orange border/focus ring, JetBrains Mono), custom orange scrollbar. All TDS styles live in `lotus-terminal.css.ts` — no runtime `<style>` injection, eliminating flash of unstyled content.
- **Message forwarding**: Forward any message to any room from the message context menu.
- **Draft persistence**: Unsent message drafts survive page reload via `localStorage` (`draft-msg-<roomId>`). Jotai in-memory atom is primary; localStorage is used as fallback on reload and cleared on send.

- **Location sharing**: Map embed view for incoming location events + static share button. Renders `m.location` events inline with a map tile.
- **Deleted message placeholders**: Redacted `m.room.message`, `m.room.encrypted`, and `m.sticker` events render as "This message has been deleted" with reason (if provided) rather than disappearing. One-line change in the `eventRenderer` filter in `RoomTimeline.tsx`.
### Room Customization
- **Personal room name overrides**: Right-click any room in the sidebar → "Rename for me…" to set a local display name visible only to you. Other members see the original name unchanged. A small pencil icon marks rooms with a custom local name. Stored in Matrix account data (`io.lotus.room_names`). Uses `io.lotus.room_names` account data key (based on MSC4431).
### Per-Message Read Receipts
