Brings the package up to date on the supabase_flutter v2 line, ahead of the v3 port.

Changes

Analyzer

• Resolve the supabase_lints findings (sort_constructors_first, lines_longer_than_80_chars and others) that failed the --fatal-infos step.

Auth API fixes

• Show readable labels and brand icons for the OIDC, custom, X and Zoom providers.
• Respect authScreenLaunchMode when linking an identity to an anonymous user.
• Initialize native Google sign in only once.
• Stay silent when the user cancels native Google or Apple sign in.
• Call SupaMagicAuth.onSuccess only for a fresh sign in.
• Forward auth state stream errors to onError instead of crashing.
• Verify a phone change code when an anonymous user adds a phone number.
• Show the password updated message after SupaResetPassword succeeds.
• Trim new passwords in SupaResetPassword, like SupaEmailAuth does when signing in.
• Deprecate SupaResetPassword.accessToken, which has no effect.

Example

• Regenerate the platform projects for current Flutter (Android moves from Groovy to Kotlin DSL Gradle files).

Dependencies

• Bump supabase_flutter to ^2.18.0.
• Allow sign_in_with_apple 8.x (>=7.0.1 <9.0.0). 8.x needs Flutter 3.41+, so the 7.x floor stays until the minimum Flutter version is raised.
• google_sign_in and font_awesome_flutter are already on their latest versions.

Verification

• flutter analyze --fatal-warnings --fatal-infos, dart format and dcm analyze are clean.
• flutter test: all 77 tests pass.
