v1.10 — Activation with key dialog, auto-refresh, Access restriction, fixes

- Product key dialog: Fluent overlay with 5-field input + paste support
- Activate button on each license card asks for key first (/inpkey + /act)
- Auto-refresh lists after removal/activation on all pages
- Access checkbox disabled for Standard and Home & Business editions
- MSI uninstall: only accept {GUID} product codes (fix msiexec help popup)
- Window height properly resets when Details expander is collapsed
