feat: chat — ⋮ room menu, typing indicator, online presence, read receipts

- RoomRow: ⋮ button (hover) for pin/unpin context menu
- MessageBubble: right-click context menu with emoji reactions + edit/delete
- Typing indicator: debounced setTyping, animated TypingDots, polling getTyping every 2s
- Online presence: heartbeat setPresence every 30s, green dot on avatars/header
- Read receipts: ✓/✓✓ for own messages in direct rooms via otherUserLastRead
- Migration 075: chat_presence + chat_typing tables
- Context menus clamped to viewport bounds
