Update flutter_cache_manager_firebase dependencies

[rickdijk]

✨ What kind of change does this PR introduce? (Bug fix, feature, docs update...)

Dependency and SDK update for flutter_cache_manager_firebase (v2.1.3).

⤵️ What is the current behavior?

• Min Dart SDK is >=3.0.0
• flutter_cache_manager constrained to ^3.4.1
• firebase_storage constrained to >=12.0.0 <13.0.0
• flutter_lints at ^4.0.0
• Other deps (path_provider, path) slightly behind latest compatible versions

🆕 What is the new behavior (if this is a feature change)?

• Raises min Dart SDK to >=3.10.0
• Updates flutter_cache_manager to ^3.4.2
• Widens firebase_storage to >=12.0.0 <14.0.0 (supports 13.x)
• Updates path_provider to ^2.1.6, path to ^1.9.1, flutter_lints to ^6.0.0
• Removes unnecessary library name (new lint from flutter_lints 6)
• Applies dart format to source files

💥 Does this PR introduce a breaking change?

Yes for consumers still on Dart SDK < 3.10.0. Apps already on Flutter with Dart 3.10+ are unaffected. firebase_storage 12.x remains supported.

🐛 Recommendations for testing

• flutter pub get in flutter_cache_manager_firebase
• dart format --set-exit-if-changed .
• flutter analyze
• Confirm resolution works with both firebase_storage 12.x and 13.x if possible
