feat: OpenClaw HTTP bridge, HA conversation agent fixes, voice pipeline tooling

- Add openclaw-http-bridge.py: HTTP server translating POST requests to OpenClaw CLI calls
- Add launchd plist for HTTP bridge (port 8081, auto-start)
- Add install-to-docker-ha.sh: deploy custom component to Docker HA via SSH
- Add package-for-ha.sh: create distributable tarball of custom component
- Add test-services.sh: comprehensive voice pipeline service checker

Fixes from code review:
- Use OpenClawAgent (HTTP) in async_setup_entry instead of OpenClawCLIAgent
  (CLI agent fails inside Docker HA where openclaw binary doesn't exist)
- Update all port references from 8080 to 8081 (HTTP bridge port)
- Remove overly permissive CORS headers from HTTP bridge
- Fix zombie process leak: kill child process on CLI timeout
- Remove unused subprocess import in conversation.py
- Add version field to Kokoro TTS Wyoming info
- Update TODO.md with voice pipeline progress
