fix(mobile): poll in-progress org review transcripts

[iscekic]

Review and merge #5985.

An in-progress org code-review transcript now loads. A finished transcript already loaded.

• Org reviews run as bot-owned sessions. A stream ticket is creator-only (web fix(code-reviews): restore live review transcripts #5781).
• The mobile spectator used a websocket for every in-flight v2 review, so org members got 403 and an empty live log.
• In-flight org reviews now poll getSessionMessages every 2s, same as web.
• Personal in-flight reviews still use the live socket.
• An empty poll does not wipe the last non-empty snapshot.

Test

• pnpm --filter kilo-app exec vitest run src/components/code-reviewer/review-spectator-behavior.test.ts src/components/code-reviewer/review-detail-screen.mounted.test.tsx
• 50 tests passed. Lint and typecheck passed.
