docs: sync category names with code and add missing schema fields

- Update category tables to match DEFAULT_CATEGORIES in constants.ts
- Remove non-existent 'most-capable' and 'general' categories
- Add 'unspecified-low' and 'unspecified-high' categories
- Update model names to full paths (e.g., openai/gpt-5.2-codex)
- Add new CategoryConfig schema fields: description, variant, top_p, etc.
- Fix atlas.ts prompt examples with correct category names
