device: add copyToClipboard and fix regenerate token HTMX button

Phase 3: Complete device page functionality fixes

- Add copyToClipboard function to device-management.ts:
  - Uses navigator.clipboard.writeText() for copying
  - Shows success/error toast notifications
  - Already exported in Alpine.store, now properly defined
- Fix typo in devices.templ: change 'regerate-token' to 'regenerate-token'
- Add HTMX support to RegenerateDeviceToken handler:
  - Returns HTML with reload script for HTMX requests
  - Preserves JSON response for API calls

The regenerate token button now works via HTMX (hx-put) instead of
Alpine.js, matching the pattern used elsewhere in the app.
