refactor: Remove emojis and band colors from codebase

- Simplify Vertical model (remove color, emoji fields)
- Update vertical-context.tsx to just slug/name
- Update band-selector.tsx (no colors)
- Update all [vertical] page routes (no emojis in headings)

Themes will be added later as a separate feature.
