feat: proxy provider UI, webhook URL fix, and dev-server key persistence

- Add proxy provider selector (None/NPM) to settings page with radio cards
- Show warning when switching to None about existing NPM routes
- Conditionally hide SSL certificate picker and NPM credentials when provider is None
- Fix webhook URL regenerate not updating UI (field name mismatch: url vs webhook_url)
- Fix dev-server.sh to persist ENCRYPTION_KEY across restarts via data/.dev-key
- Fix selected radio card background visibility in dark mode
