fix(server): clean up test suite — remove mocks, delete redundant tests, fix races

- Remove vi.mock() from provider-launch-config.test.ts, use dependency injection instead
- Delete codex-app-server-agent.test.ts integration infrastructure (1900 lines) —
  real codex coverage lives in daemon e2e tests (agent-basics, permissions-codex, etc.)
- Delete claude-agent-commands.test.ts — redundant with daemon e2e suite
- Delete 16-agent-update.test.ts — tested removed functionality
- Fix getAvailablePort race condition with port 0 in bootstrap.ts
- Extract large integration test blocks from unit test files into daemon e2e
- Clean up speech-runtime TTS manager test to use real dependencies
- Net -2258 lines across 17 files, all tests passing
