fix: stabilize all test suites after v14 breaking changes (#3039)

## Summary

- Fix all 67 failing test suites (506 tests) caused by v14 breaking
changes
- Resolve circular dependency chains in MessageComposer barrel imports
- Add missing React imports
- Add JSDoc warning to useDebouncedTypingActive about user?.id
requirement
- Upgrade EventEmitterMock and MediaRecorderMock to support realistic
event dispatch
- Migrate all Preview, List, Avatar prop usages in tests to
WithComponents overrides

## Test plan

- [x] yarn jest -- 142/142 suites pass, 1977/1977 tests green, 0 skipped
- [x] yarn lint-fix passes
- [ ] yarn types
- [ ] yarn build

### Categories of test fixes

| Category | Suites | Changes |
|---|---|---|
| Missing DialogManager context | ~10 | Added Chat or
DialogManagerProvider wrappers |
| Avatar prop renames | ~15 | image to imageUrl, name to userName, added
size |
| Component renames | ~10 | ReactionsList to MessageReactions,
MessageDeleted to MessageDeletedBubble, etc |
| Removed context fields | ~8 | Removed editing, updated handleDelete
signature, cooldown API migration |
| Stale snapshots | ~25 | Regenerated snap files, replaced inline
snapshots with structural assertions |
| Missing mocks | ~10 | Added useChatViewContext, useThreadContext,
deleteDraft mocks |
| Behavioral changes | ~5 | Mobile nav viewport check, action renames,
mention UI changes |
| AudioRecorder integration | 2 | Rewrote upload/submit tests to use UI
interactions |
| WithComponents migration | ~2 | Replaced Preview, List, Avatar,
LoadingErrorIndicator props with WithComponents overrides |

### Production code changes

| File | Change |
|---|---|
| Dialog/Alert.tsx, MessageComposer/QuotedMessageIndicator.tsx | Added
missing import React |
| ~14 files across MediaRecorder, TextareaComposer, Poll, Location |
Barrel to direct imports to break circular deps |
| TypingIndicator/hooks/useDebouncedTypingActive.ts | Added JSDoc
warning about user?.id requirement |

### Mock infrastructure improvements

| File | Change |
|---|---|
| mock-builders/browser/EventEmitter.js | Now stores listeners and
supports emit() for realistic event dispatch |
| mock-builders/browser/MediaRecorder.js | Tracks state transitions;
autoEmitDataOnStop static flag simulates browser stop to dataavailable
flow |

### Known follow-up

- Circular dependency root cause: Children of MessageComposer call
useMessageComposerController() instead of reading the controller from
context
