chore: upgrade melos to 7.5.1 with pub workspaces and dep catalog

- Upgrade Melos to 7.5.1 using Dart pub workspaces (Melos 7 paradigm).
- Replace per-package pubspec_overrides.yaml with workspace-native resolution. Add dependencies.yaml as a centralized catalog for all external deps with sync_deps.dart tool to propagate and validate versions across the monorepo.
