feat(api): add extended pet profile fields — schema, migration, CRUD, Zod validation
Adds five new nullable columns to the pets table:
- coat_type (text)
- temperament_score (integer, range 1–5)
- temperament_flags (jsonb, string[])
- medical_alerts (jsonb, typed MedicalAlert[])
- preferred_cuts (jsonb, string[])
Also:
- Exports MedicalAlert interface and MedicalAlertSeverity type from schema
- Updates shared Pet type in packages/types
- Adds Zod validators for all fields (ranges, max lengths, enum)
- Adds 14 tests covering happy path and validation edge cases
- Fixes drizzle.config.ts schema path (was ./src/schema.ts, correct is ./src/db/schema.ts)
