The deployed migration crash-looped PocketBase (502 on every /api call)
for two reasons, both verified against a production-like DB locally:
1. team_members is referenced by relation fields (team_member_id) in
micro_learning_completions and theme_session_completions, so
app.delete(team_members) was blocked — and the swallowed error left
the create to fail with "Collection name must be unique". Fix: before
dropping team_members, convert those relation fields to plain text
(consistent with how user_id is stored elsewhere) and rebuild the
theme_session_completions unique index on the text column.
2. An enabled OAuth2 provider with empty clientId/clientSecret fails
validation and aborts the migration. Fix: attach the OIDC provider
only when ENTRA_CLIENT_ID and ENTRA_CLIENT_SECRET are present;
otherwise create the auth collection without a provider.
Verified locally with the muchobien/pocketbase image: boots clean both
without Entra env (provider-less) and with env (auth-methods returns the
Microsoft OIDC provider).
