improve: add image/video share and run share commands silently (#3330)

* improve: add image/video share and run share commands silently

- Added 'image' and 'video' modes to omarchy-cmd-share to quickly send
  the most recent screenshot or video without selecting manually.
- Updated show_share_menu to run share commands in the background using
  'nohup' to avoid opening a terminal window.
- Comments added to explain each section for clarity and maintainability.

* Match names with folders

* Correct here too

* Don't need to keep this around

* Fix these up for what's needed only
