refactor: remove theme from ztools, move to base distribution

- Delete CatppuccinMocha preference pack (redundant with KindredCreate)
- Delete theme.py (generate_stylesheet never called; apply_spreadsheet_colors
  was a no-op due to SetUnsigned vs GetASCII type mismatch)
- Remove preferencepack declaration from package.xml
- Remove apply_spreadsheet_colors call from InitGui.py Activated()
- Clean up resources/__init__.py exports

Spreadsheet colors are now set via KindredCreate.cfg preference pack
using FCText entries that match the C++ GetASCII() reader.

Part of #278

CatppuccinMocha/CatppuccinMocha.cfg
