kbe da3522d118 feat: Implement SEO-friendly slug generation and improve geocoding UX
- Add Rails parameterize for server-side slug generation (name-venue-city format)
- Configure client-side slug library with RFC3986 mode for consistency
- Remove slug field from edit forms to prevent URL changes after publication
- Enable image_processing gem for Active Storage variants
- Make geocoding notifications visible indefinitely on promoter event forms
- Add server-side slug generation fallback with uniqueness validation
- Update promoter controller to allow slug only for new events
