Dev seed script creates 8 accounts, 8 members, 16 repair templates,
6 repair tickets in various statuses, and a school batch with 5
instruments. Run with bun run db:seed-dev.
Batch detail page now has a status progress bar matching the ticket
detail pattern. Add Repair from batch pre-fills the account and
contact name. New repair form reads accountId and contactName from
search params when linked from a batch.
