GRO-1921: seedUatStaffAccounts() shared fn — full UAT seed honors numeric OIDC subs

Extract UAT staff account seeding into a shared async function so it
runs in both seedKnownUsers() and the full seed() UAT branch.

Before this change the full seed() UAT path never created the
deterministic UAT staff (UAT Super/Staff/Groomer) with their numeric
oidcSub values from SEED_UAT_*_OIDC_SUB env vars — seedKnownUsers()
had that logic but was bypassed by SEED_KNOWN_USERS_ONLY=true in the
UAT reset CronJob.

seedUatStaffAccounts() handles:
- UAT Super Staff (SEED_UAT_SUPER_OIDC_SUB)
- UAT Staff Groomer (SEED_UAT_STAFF_OIDC_SUB)
- UAT Groomer Personas (SEED_UAT_GROOMER_EMAILS + _NAMES)
- Better Auth email+password credentials (SEED_UAT_*_PASSWORD)
- UAT Customer client + 2 pets
