feat: enable proxy toggle on quick deploy, event log clearing, and UX fixes

- Add enable_proxy toggle to Quick Deploy form (defaults to on)
- Add DELETE /api/events/log/{id} and DELETE /api/events/log endpoints
- Add Clear All button with confirmation on Events page
- Rename "NPM Proxy" to "Enable Proxy" on stage form (provider-agnostic)
- Fix polling interval validation (min 60s) and number input trim errors
- Fix domain field no longer required in settings
