Migrate MavenDownloaderImpl to use MIMA (Minimal Maven) 2.4.39

- Replace manual Maven Resolver setup with MIMA library
- Remove DIRegistry and manual DI configuration (~650 lines)
- Reduce MavenDownloaderImpl from 1,240 to 649 lines (48% reduction)
- Add MIMA dependencies (context, embedded-maven, standalone-static)
- Remove individual maven-resolver-* dependencies
- Preserve all existing functionality:
  - Dual mode operation (embedded Maven plugin + standalone)
  - Repository configuration (Maven Central, Apache Snapshots, custom repos)
  - Settings.xml and settings-security.xml processing
  - Offline mode, fresh mode, repository resolver
  - Download listeners and custom timeout configuration
- Update MavenVersionManager and ValidateMojo to use new constructor
- Delete obsolete DIRegistry, DIRegistryTest, and MavenResolverTest
