Adds a seeding step after UAT staff creation that:
- Creates Better-Auth user records (emailVerified: true) for 4 UAT accounts
- Creates account records with providerId="credential" and scrypt-hashed passwords
- Links staff.userId for accounts with existing staff records (super, groomer, tester)
- Reads passwords from SEED_UAT_*_PASSWORD env vars (guard clause skips if unset)
- Is fully idempotent (upsert-safe)
Bypasses Authentik SSO for UAT login; Shedward can authenticate via
POST /api/auth/sign-in/email using the same UAT password secrets.

Created comprehensive UAT playbook covering all 13 route groups with test cases for authentication, client management, pet management, appointment scheduling, services, staff management, invoicing & payments, customer portal, waitlist, search, reports, impersonation, and settings & setup.
