feat: switch from PaperMod to Congo theme

- Warm avocado color scheme, light mode default — friendly for families
- Congo language configs in config/_default/languages.{en,de}.toml
- Renamed extend partials to Congo convention (hyphens)
- Override warnings.html for Hugo 0.159 compatibility (.Author removed)
- All shortcodes and custom partials preserved
