feat(tui): overhaul theme palette for legibility

Replace Nord and Gruvbox with Rosé Pine and Dracula. Add Kanagawa
and Everforest. Fix legibility issues across remaining themes:

- Tokyo Night: separate Muted from Fg, distinct SelectedBg
- Catppuccin Mocha: bolder semantic colors, tighter zebra, distinct SelectedBg
- Order themes by warm→cool color temperature for smooth cycling
