fix(GRO-1272): auto-provision staff record on first OIDC login

When a user authenticates via OIDC but has no staff record (userId NULL,
oidcSub mismatch, email mismatch), resolveStaffMiddleware now checks for
a Better-Auth user record by jwt.sub and auto-creates a minimal groomer
staff record on first login.

This fixes the UAT regression where all API routes returned 403 for all
authenticated users after GRO-1207, because seedKnownUsers() sets
oidcSub to Authentik integer PKs or emails rather than the actual Authentik
OIDC sub (a UUID). The auto-provision path bridges the gap for all UAT
personas without requiring seed/Terraform changes.
