WHAT

Improve UI/UX and key binding descriptions

• Update help text for navigation keys (g, G, u, d) to be more consistent
• Add toggle between "Deleted From" and "Trash Path" view in detail screen
• Change space key description from "info" to "detail"
• Change @ key description from "datefmt" to "info"

WHY

This change was added to improve user experience by:

1. Making it easier for users to understand both the original and current locations of deleted files:
   • Before: Users could only see where the file was deleted from
   • After: Users can toggle between the original location ("Deleted From") and where it's currently stored ("Trash Path")
2. Addressing a likely user need:
   • When restoring files, users might want to verify both:
     • Where the file originally came from
     • Where it's currently stored in the trash
   • This is especially useful for troubleshooting or when managing multiple trash locations

The toggle feature (using the @ key) provides a simple way to access both pieces of information without cluttering the interface.
