feat: [IOPID-3214] Offline wallet: startup timeout scenario

[Ladirico]

Short description

This PR introduces the handling of the timeout case during the app startup loading.
When the app fails to connect within the expected time, the user is offered the option to access the Wallet in offline mode.
Unlike other offline reasons, this case only displays a banner with a refresh action and does not trigger a bottom sheet.

List of changes proposed in this pull request

• Added specific handling for OfflineAccessReasonEnum.TIMEOUT.
• Displayed a banner with refresh action for the timeout scenario.
• Prevented the bottom sheet from being rendered when the reason is timeout.
• Updated translations for the new timeout alert messages.

Demo

Local .env. (iOS)	Prod .env (Android)
Registrazione.schermo.2025-08-28.alle.10.15.12.mov	android.mov

How to test

1. Start application
2. Simulate a startup timeout (use proxyman or your internet connection)
3. Verify that:

• A banner is displayed with the correct timeout content and refresh action.
• No bottom sheet is displayed.
• The refresh action correctly restarts the app.

4. Verify that other offline reasons (device_offline, session_expired, session_refresh) still show the banner + bottom sheet as expected.
