fix(HealthColors): Fix aura visibility threshold and improve settings menu interaction

- Fixed aura visibility threshold for tokens at or above the configured HP threshold, ensuring correct aura behavior.
- Updated `!aura` settings menu to always show the interactive GM menu after changes, resolving issues with read-only panels.
- Enhanced token refresh logic to immediately re-evaluate existing tokens when the HP threshold changes.
- Removed unused `applyDefaultAura` function and cleaned up redundant code.
- Refactored command dispatch in `handleInput` to reduce boilerplate and improve readability.
- Updated progress messages to reflect the script name and changed terminology for clarity.
