refactor: break up app.js into smaller modules

Split static/js/app.js (581 lines) into 5 focused modules:
- utils.js: global utilities store + legacy compat
- components.js: reusable Alpine.js components (copy, confirm, dismiss, time)
- app-detail.js: app detail page logic (status polling, logs)
- deployment.js: deployment card + deployments history page
- dashboard.js: dashboard relative time updates

Closes #128
