feat(db): add 0037_add_extra_large_to_pet_size_category — register extra_large in journal

GRO-1979: The pet_size_category enum created in 0031_buffer_rules.sql
contained ('small', 'medium', 'large', 'xlarge'), but the drizzle schema
and seed.ts both use 'extra_large'. The mismatch caused the UAT seed job
to fail with:
  invalid input value for enum pet_size_category: "extra_large"

This migration adds the 'extra_large' value to pet_size_category and
registers it at idx 37 in the drizzle journal (sequel to 0035/0036
which registered short/medium/silky in coat_type under GRO-1971).

Non-transactional per Postgres restriction on ALTER TYPE ADD VALUE.

+-- GRO-1979: Adds the 'extra_large' value to the pet_size_category enum.

+-- ('small', 'medium', 'large', 'xlarge'), but seed.ts and the drizzle
+-- schema (PetSizeCategory type) both use 'extra_large' — a mismatch that

+--
+-- 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.
