feat: MC detail popup, image crop editor, empty dates support

Master Classes:
- Detail popup on card click with description, all dates, location+address
- Card shows only first date (or "Скоро" if no dates)
- Trainer name clickable to open bio
- Text backdrop panel on cards for readability
- No photo overlay darkening
- Fix crash when MC has no/empty slots
- Price "BYN" no longer duplicated
- Admin: ImageCropField replaces PhotoPreview (with focal/zoom)
- Admin: RichTextarea for description
- Admin: photo+fields side-by-side layout, fixed photo width

Pricing:
- Added rentalSubtitle field for rental tab info
