feat: Flyway V3 pet_health 结构基线 + V4 字典种子 + pet 域错误码（T2-01）

- V3：pet_health schema 8 张表（breeds/pets/pet_owners/pet_weight_records/
  vaccine_catalog/pet_vaccinations/health_events/care_reminders），列、CHECK、
  部分唯一索引、updated_at 触发器与目标模型一致
- 强制裁剪：剥离 bootstrap SQL 1156~1166 行 4 条指向 marketplace 的跨 schema
  外键（provider_id/booking_id 保留为裸可空 uuid，M5 迁移 marketplace 时补回）
- ADR-010：health_event_media 不建（media 剪出 M2，纯增量表后续补零成本）
- V4：breeds（28 条）与 vaccine_catalog（10 条）字典种子，生产参考数据走正式
  迁移链不放 db/dev；正典目录内容由产品侧供稿（D2-6）
- ErrorCode 预置 pets 域四码：40300 PET_ACCESS_DENIED、40401 PET_NOT_FOUND、
  40402 RECORD_NOT_FOUND、40902 VERSION_CONFLICT（第二波接口直接消费）
- 新增 PetHealthMigrationIntegrationTest：干净 postgres:18 上全量迁移验证
  表数、结构抽查、4 条 FK 确不存在、触发器与种子数据

+/*
+ V3 baseline: pet_health schema (M2 宠物健康档案), extracted from
+ patbond-doc/docs/database/patbond_postgresql.sql (reviewed target model,
+ lines 333-554) per iteration-2 T2-01.
+
+ Scope notes:
+ - 8 of the 9 pet_health objects are created here: breeds, pets, pet_owners,
+   pet_weight_records, vaccine_catalog, pet_vaccinations, health_events,
+   care_reminders.
+ - pet_health.health_event_media is NOT created (ADR-010: media/attachments
+   are cut from M2; the table's asset_id is a NOT NULL FK to media.assets and
+   the media upload flow does not exist yet). It is a pure additive table and
+   will be introduced by a later migration together with the media work.
+ - Cross-schema FKs into marketplace are STRIPPED (mandatory cut, T2-01):
+   the target model adds these four constraints at lines 1156-1166 —
+     * fk_vaccinations_provider  (pet_vaccinations.provider_id -> marketplace.providers)
+     * fk_vaccinations_booking   (pet_vaccinations.booking_id  -> marketplace.bookings)
+     * fk_health_events_provider (health_events.provider_id    -> marketplace.providers)
+     * fk_health_events_booking  (health_events.booking_id     -> marketplace.bookings)
+   The marketplace schema belongs to M5 and is not migrated in M2. The four
+   columns are kept as bare nullable uuid; the constraints will be re-added
+   by the M5 migration that creates the marketplace schema (M5 补回).
+ - FKs to identity.users and media.assets are kept as-is: both schemas exist
+   since V1 (same precedent as media.assets.owner_user_id in V1).
+ - updated_at triggers reuse platform.set_updated_at() created in V1.
+ - Structure only; the breeds / vaccine_catalog dictionary seed rows are
+   production reference data and live in V4 (not in db/dev).
+ - Never edit this file after release; subsequent changes go into V4+.
