The per-persona Entra oid map consumed by prisma/seed.ts was missing
the matching ignore pattern when the personas seed work landed.
infra/test-tenant.personas.json has been showing up as untracked
(??) across multiple sessions, exposing it to an accidental
'git add .'. Mirror the existing *-tenant.entra.json pattern:
ignore the tenant-private file, keep the .example.json template
tracked.
Verified via 'git log --all -- infra/test-tenant.personas.json'
that no commit ever referenced this path, so no history rewrite
needed — pure forward-only fix.
