ci(test): run the server integration suite against real Postgres/Redis (#159)

The only test command in CI was `pnpm -r test` (unit `.spec.ts` on mocks).
`test:int` (`.int-spec.ts`, real Postgres/Redis) ran nowhere in CI — there
were no DB `services:` — so the cost-cap, FK-cascade, jsonb round-trip and
real AI-apply integration tests never gated a PR, and regressions in those
high-severity paths stayed green (red-team finding #7).

Add `services: postgres (pgvector) + redis` and a `pnpm --filter server
test:int` step. The pgvector image is required because migrations create
vector columns and global-setup runs `CREATE EXTENSION vector`. Service
credentials/db match the defaults in apps/server/test/integration (docmost /
docmost_dev_pw, maintenance db `docmost`, redis 6379), so no TEST_*_URL
overrides are needed; global-setup drops/recreates the isolated docmost_test
DB and migrates it.

NOTE: the workflow change itself can only be validated by an actual CI run
(YAML parses locally); the int-spec suite is verified passing locally on this
branch.
