Add Moonbase Alpha (light) and rename dark to Moonbase Bravo

Split the Moonbase theme into a complementary pair:
- Moonbase Alpha: warm cream/stone light theme with deep gold accents
- Moonbase Bravo: the original deep charcoal dark theme

Both share the same gold (#d4a039) brand accent, copper error states,
and earthy neutral palette. Alpha uses darkened gold (#9a7420) for
better contrast on light backgrounds.
