Khalid Abdi 15fc7fdf26 feat(messages): attach files and share appointments
- new message_attachments table + POST/GET /api/conversations/attachments
  (base64 upload, capped 10MB; authed clinic-scoped download)
- messages carry an attachments JSON column (file refs or appointment
  snapshots); realtime + REST send accept attachments and allow
  attachment-only messages; migration 0019
- composer "+" menu (Files / Appointments): file picker uploads and
  stages chips; appointment picker searches by patient and attaches a
  snapshot; both render in the thread (download chip / appointment card)
- raise express json limit to 15mb for base64 uploads
