Fix video comment effect wrapping (#5748)

## What changed

- render video-review timecode chips inside the first Markdown paragraph
so comment text wraps naturally around them
- reuse the canonical video-review chip treatment across the timeline,
Inbox previews, and Inbox detail
- preserve video-review context in Inbox so timestamp chips remain
interactive

## Why

Video comments now support Markdown-like effects, but non-player
surfaces rendered the timestamp beside a separate text layout. That kept
the chip and comment from sharing the same inline flow and made Inbox
behavior inconsistent with the player.

## Validation

- `pnpm --dir desktop check`
- 100 focused Markdown, timecode, video-review, and Inbox unit tests
- `pnpm --dir desktop build:e2e`
- focused `video-attachment.spec.ts` Playwright scenario
- pre-push desktop typecheck and 4,761-test desktop suite
- native Builderlab staging with the configured profile

Focused timeline and Inbox snapshots will be attached in a PR comment.
