Login Screen

Single screen offering email/phone + password, plus Google and Apple buttons. Listens to loginNotifierProvider for the per-method loading flags so each button can show its own spinner independently.

1. User picks auth method (email or phone) via AuthMethodNotifier.
2. Enters credentials → submits → ref.read(loginNotifierProvider.notifier).login(...).
3. loginNotifierProvider streams state — isPasswordLoading toggles the submit button spinner.
4. On state.isAuthenticated the GoRouter redirect fires and navigates to /home.
5. On state.error a SnackBar surfaces the unwrapped exception message.

• Three independent loading flags (password / google / apple) prevent cross-method spinner flicker.
• Apple button is conditionally rendered on iOS only — Android shows Google only.
• Google cancellation must not surface as an error — the notifier returns false but leaves state.error null.

Phone-based password login is part of the UI toggle but the backend currently only supports email — picking 'phone' falls back to email validation messages.
