Fix build errors and improve code quality

Address CI build failures and additional code review suggestions:

**Build Fixes:**
- Add CustomStringConvertible conformance to SimpleClickEngine.ClickType
- Fix NSSize os.log interpolation by using String(describing:)

**Code Quality Improvements:**
- Create LoggingConstants enum for shared subsystem string
- Prevent typos and ensure consistency across logging
- Derive cursor resource file name from cursorDimension constant
- Move cursor properties to top of setupCustomCursor() for easy modification

This ensures the code builds cleanly and follows Swift best practices
for maintainability and consistency.
