Add ProposedFilenameView and MediaPanelView with comprehensive tests

- Implemented ProposedFilenameView to generate standardized filenames using a decorator pattern.
- Created MediaPanelView to assemble media data panels for display, aggregating multiple formatters.
- Added tests for ProposedFilenameView covering various formatting scenarios, including basic, minimal, and special cases.
- Introduced a views package to organize and expose the new views.
- Ensured proper formatting and display of media information, including file info, TMDB data, and track information.
