fix(db): add extra_large to pet_size_category enum (GRO-1999)

GRO-1999: UAT seed-test-data job (image 2026.05.31-5390131) crashes with
22P02 'invalid input value for enum pet_size_category: "extra_large"'.
seed.ts petSizeCategoryPool and the drizzle schema both use
'extra_large', but migration 0031_buffer_rules.sql created the enum
with 'xlarge' instead — same migration drift pattern that GRO-1971
fixed for coat_type.

Add migration 0037_add_extra_large_to_pet_size_category.sql that
ALTERs the enum to add the missing 'extra_large' value (idempotent,
auto-commit because Postgres forbids ALTER TYPE ADD VALUE inside a
transaction block). Register idx 37 in the drizzle journal.

Mirror the UAT_PLAYBOOK entry from GRO-1971: TC-API-3.28 verifies the
pet_size_category enum has all 4 values used by seed.ts after the seed
job completes, so future enum drift is caught at the UAT gate.

Refs: GRO-1950 (UAT regression that surfaced this), GRO-1971
(pattern this fix mirrors), GRO-1979 (parallel fix landed on a
different branch via PR #124 — this is the GRO-1983 baseline equivalent).
