Code review fixes: wardrobe migration, response validation, path traversal guard, deduplication

- Migrate 11 character JSONs from old wardrobe keys to _BODY_GROUP_KEYS format
- Add is_favourite/is_nsfw columns to Preset model
- Add HTTP response validation and timeouts to ComfyUI client
- Add path traversal protection on replace cover route
- Deduplicate services/mcp.py (4 functions → 2 generic + 2 wrappers)
- Extract apply_library_filters() and clean_html_text() shared helpers
- Add named constants for 17 ComfyUI workflow node IDs
- Fix bare except clauses in services/llm.py
- Fix tags schema in ensure_default_outfit() (list → dict)
- Convert f-string logging to lazy % formatting
- Add 5-minute polling timeout to frontend waitForJob()
- Improve migration error handling (non-duplicate errors log at WARNING)
- Update CLAUDE.md to reflect all changes
