feat: remove additional useless module artifacts

Remove remaining modules that only contained i18n translation files:
- muk_web_theme, muk_web_colors, muk_web_dialog, muk_web_chatter, muk_web_appsbar
- base_geoengine

These are translation artifacts from modules that exist in other repositories:
- MuK modules are maintained separately
- base_geoengine is from OCA (geospatial modules)

This completes the cleanup of all useless module artifacts.
