docs(UAT_PLAYBOOK): note GRO-1977 seed idempotency fix for TC-API-1.4-1.7

Updated UAT_PLAYBOOK.md §4.1 — add note that seed credential provisioning
is idempotent and TC-API-1.4 through TC-API-1.7 now return 200 for all
4 UAT personas (previously returned 401 due to frozen-hash bug).

--- Migration: 0037_add_extra_large_to_pet_size_category.sql
--- GRO-1979: Adds the 'extra_large' value to the pet_size_category enum.
---
--- 0031_buffer_rules.sql created pet_size_category with values
--- ('small', 'medium', 'large', 'xlarge'), but seed.ts and the drizzle
--- schema (PetSizeCategory type) both use 'extra_large' — a mismatch that
--- caused the UAT seed job to fail with:
---   invalid input value for enum pet_size_category: "extra_large"
---
--- 0035/0036 (GRO-1971) registered 'short'/'medium'/'silky' in coat_type.
--- This migration is the pet_size_category counterpart: register
--- 'extra_large' so seed.ts can write the value the schema declares.
---
--- Postgres restriction: ALTER TYPE ADD VALUE cannot run inside a
--- transaction block. The drizzle migrate runner does not wrap
--- individual statements in an explicit transaction, so this applies
--- as a single auto-commit DDL.
