Code refactoring.

Fixed missing restraint toggle gizmo (UI only, no save impact).

Fixed some missing files.

Cleaned up unnecessary files and folders.

This update applies to RimWorld 1.6 only.

Changed storage of slave duration
-Now stored in CompSlave instead of TimeAsSlave.
-Original record is kept for compatibility, updated only on save.
-Prevents record index corruption when adding/removing DLCs or mods.

One-time migration
-Existing TimeAsSlave values are migrated once to CompSlave with a toast notification.

UI change
-Accurate slave duration is now shown in the character Inspect panel.
-Slave stage is also displayed if enabled in settings.

Cleaned up unnecessary files and folders.

The previously added debug action to edit a pawn’s TimeAsSlave value is now supported on RimWorld 1.5 as well.

Added a temporary debug action that lets you directly edit a pawn’s TimeAsSlave value in-game.
Cleaned up the folder structure for better readability and maintainability.
Tidied up parts of the code and removed unnecessary bits.

While acting as wardens, slaves can no longer perform "Slave Suppression," "Slave Emancipation," "Slave Imprisonment," or "Slave Execution" actions on themselves.

Improved icon image clarity
Corrected file name typos
