feat(gui, tauri): Save settings in Tauri storage

[binarybaron]

• Implemented dual persistence strategy:
  • User Settings: Persisted across app restarts using tauri-plugin-store.
  • Transient State: Persisted across page reloads using sessionStorage.
• Added settingsSlice reducer for managing persistent user settings.
• Updated Redux store configuration to handle multiple persistence layers.
• Added a new Settings page in the GUI where users can specify custom Electrum RPC URLs for Bitcoin and Monero node URLs.
  • Users can input their preferred Electrum server (ssl://host:port) and Monero daemon (http://host:port).
  • Input fields include validation to ensure correct URL formats.
  • Settings persist across application restarts using Tauri's storage plugin.
  • A reset option is available to revert to default settings.
• Improved the Daemon Controller in the Help page:
  • Renamed RpcControlBox to DaemonControlBox for clarity.
  • Users can now start the daemon manually if it isn't running or has failed.
  • Added a "Restart GUI" button to apply new settings immediately.
  • Displayed the daemon's status within the controller.
• Upgraded Tauri and related plugins to stable version 2.0.0:
  • Updated tauri, tauri-build, and tauri-utils to 2.0.0.
  • Ensured compatibility with the latest stable release.
• Updated Tauri plugins to version 2.0.0:
  • tauri-plugin-clipboard-manager
  • tauri-plugin-shell
  • Added new plugins:
    • tauri-plugin-store for settings persistence.
    • tauri-plugin-process to enable application relaunch.
• Deferred Context initialization until explicitly triggered from the frontend.
  • Moved Context setup from the setup function to a new initialize_context Tauri command.
  • Allows the application to start without immediately initializing the backend context.
  • Context initialization now considers user-provided settings for Electrum and Monero nodes.
• Introduced a ValidatedTextField component for form inputs with validation logic.
  • Provides immediate feedback on input validity.
  • Used in the Settings page for Electrum and Monero node URLs.
• If the user provides an override Monero remote daemon, we check if it reachable and on the correct network before starting the monero-wallet-rpc
• Changed bitcoin_confirmation_target type from usize to u16.

@Einliterflasche You wanna implement the UI side of this? You could also add an option for different themes (real dark mode, ...)
