fix(db): re-register 0034/0036 schema changes via idempotent 0039/0040 (GRO-2033)

Prod cumulative promotion 2026.06.01-7667288 (PR #596) revealed that
0034_extend_pet_profile_columns (temperament_score + 3 jsonb cols) and
0036_add_missing_coat_type_values (short/medium/silky) were silently
skipped on the prod database, leaving the seed/reset path with:

  Seed failed: PostgresError: column "temperament_score" does not exist

## Root cause: drizzle high-water-mark, same shape as GRO-1999

drizzle-orm@0.38.4 `pg-core/dialect.js#migrate` only applies a journal
entry when its `folderMillis` is strictly greater than the most recent
`__drizzle_migrations.created_at`:

  if (!lastDbMigration || Number(lastDbMigration.created_at) < migration.folderMillis) {
    // apply SQL + record hash
  }

`packages/db/migrations/meta/_journal.json` has 0033's when at
1779500000000 (2026-05-23) — but 0034 was registered with when
1751140800000 (2025-06-28) and 0036 with 1751480000000 (2025-07-02).
Both are below the 0033 watermark, so on the prod DB (whose newest
applied migration was 0033) drizzle silently skipped 0034 and 0036.
0038 (when 1780000000000) was above the watermark, so it applied — and
the migrate Job exits 0 with 'migrations applied successfully!'. The
schema didn't change. GRO-1999 documented the same bug for 0037 → 0038.

UAT/dev are unaffected because their watermarks were already below the
0034/0036 entries when those originally ran.

## Fix

Add two new idempotent migrations with monotonic 'when':

- 0039_extend_pet_profile_columns_idempotent.sql, when 1780000000001:
    ALTER TABLE pets ADD COLUMN IF NOT EXISTS temperament_score integer;
    -- + temperament_flags jsonb, medical_alerts jsonb, preferred_cuts jsonb
- 0040_register_missing_coat_type_values.sql, when 1780000000002:
    ALTER TYPE coat_type ADD VALUE IF NOT EXISTS 'short';
    -- + 'medium', 'silky'

Both are 'IF NOT EXISTS' — safe no-ops on UAT/dev where 0034/0036
applied normally, and effective forward-fix on prod where they were
skipped. Do NOT modify 0034/0036 in place (per the GRO-1999 pattern):
UAT/dev have already applied them and re-running would fail.

## Verification

- packages/db/migrations/meta/_journal.json now has 41 entries with idx
  39 and 40 strictly monotonic in 'when'.
- python3 -c 'import json; json.load(open(...))' parses cleanly.
- ALTER TYPE ADD VALUE IF NOT EXISTS is permitted inside a tx on
  PostgreSQL 18.3 (prod cluster image confirmed via CNPG status).

## UAT Playbook

No user-visible behaviour change — schema only. Existing TC-API-3.8 / 3.9 /
3.11 / 3.13 (extended pet profile) and 3.19a (profile summary) continue to
pass and now ALSO act as smoke tests after the prod image roll-forward.
