Keep all burst images, use last timestamp as passage time

- passage_images table stores every image in a burst sequence
- Passage timestamp = last image (chronologically) in the burst
- Review UI: image slider to browse all burst images, slider ends
  at the official passage time (rightmost = last image)
- API: GET /api/passages/{id}/images
