feat(ST-702): vendor Scrum4Me schema via submodule + sync script

- Add vendor/scrum4me as a git submodule (read-only source of truth)
- scripts/sync-schema.sh copies schema.prisma into prisma/, stripping
  the upstream prisma-erd-generator block we don't ship
- Track the synced schema in git so a fresh clone works after
  'git submodule update --init && npm install'
- postinstall runs 'prisma generate' so @prisma/client is ready
