fix(audit-ai): Add dynamic fallback for unknown action_types in content generation

AI analysis generates action_types dynamically (e.g. add_sitemap, add_nap)
that don't always match predefined CONTENT_PROMPTS. Added fallback that
builds a generic prompt using the action title/description from the DB.
