Agent version tracking — workers tab shows current vs latest version

- Add version column to registered_agents table
- Agents send version on registration (Linux 3.1, Windows 3.0, macOS 3.0)
- workers_list API returns latest_versions per platform
- Workers tab: VERSION column with green check (up-to-date) or red (outdated)
- Outdated agents highlight row and show blue UPDATE button
- Up-to-date agents show dimmed UPDATE button
- Update button dispatches update command immediately
