Minimalist UI: hide all elements until activated; add help modal and keyboard shortcuts

- Redesign UI to be invisible by default: only header + '?' button shown
- Press m to show sidebar, t for toolbar, / for search, ? for help
- Add help modal with all keyboard shortcuts
- Fix scanner to skip corrupt/unprobeable files instead of aborting
- Fix scanner to skip thumbnail errors instead of aborting
- Fix rescan to use background context so it completes after HTTP response
- Rename project from KISS Media Player to Player
