Restructure layout: search in sidebar, upload in header

- Removed toolbar (Library title, search, upload button) from library
- Moved search box into the sidebar alongside Year/Genre filters
- Removed 'Filters' heading from sidebar
- Replaced 'Library' nav button in header with '+ Upload' button
- Genre filters now sorted by count (desc) instead of alphabetically
- Cleaned up unused CSS
