Add real-time deployment updates and refactor JavaScript

- Add deploy stats (last deploy time, total count) to dashboard
- Add recent-deployments API endpoint for real-time updates
- Add live build logs to deployments history page
- Fix git clone regression (preserve entrypoint for simple clones)
- Refactor JavaScript into shared app.js with page init functions
- Deploy button disables immediately on click
- Auto-refresh deployment list and logs during builds
- Format JavaScript with Prettier (4-space indent)
