Add Windows toast notifications via WinRT

[ardevdevts]

What changed

Implements the Windows backend for the existing notification system: session finished/needs-input banners (plus due reminders) now dispatch through the WinRT toast API via tauri-winrt-notification, with click-to-open-session and a Settings entry that deep-links to Windows notification settings. macOS/Linux behavior is unchanged.

Why

The notification commands returned Unsupported on Windows, so turn-finished and reminder banners silently fell back to the in-app cue only. Windows 10/11 can show native toasts like the other platforms once an AppUserModelID path exists.

UI

No layout change. The Settings Notifications blocked row now also offers its Open System Settings button on Windows (previously mac-only); the button opens ms-settings:notifications.

📝 Walkthrough

Walkthrough

The change adds Windows WinRT notification permission detection, blocked-toast handling, notification activation support, Windows reminder opening, system-settings access, and window restoration after notification clicks.

Changes

Windows notifications

Layer / File(s)	Summary
Windows notification backend src-tauri/Cargo.toml, src-tauri/src/notifications.rs	Adds WinRT notification dependencies. Platform permission commands now receive AppHandle. Windows checks WinRT toast settings and stops blocked notifications before dispatch.
Windows notification activation src-tauri/src/reminders.rs, src/App.tsx, src-tauri/capabilities/default.json	Windows includes notification reminder opening. Notification clicks unminimize the window before focusing it. The default capability allows both window operations.
Windows notification settings action src/surfaces/SettingsView.tsx	The blocked-notification view shows the system-settings action on Windows and macOS.

@ardevdevts thanks for the work. Overall this is great however I found two issues before merge:

1. The backend always returns Granted, so the Windows “Open System Settings” button never appears when notifications are blocked. It also means a blocked toast may be treated as delivered, skipping the in-app cue.
2. Clicking a notification while MonoCode is minimized only calls setFocus(). On Windows, the window must be unminimized first, otherwise it remains minimized.

Could you address these cases? 🙏

@ardevdevts Thanks for the updates. I checked the latest changes and both issues are resolved. Looks good to me.
