feat(backend): add integration tests with testcontainers-go

Add internal/integration/server_test.go covering the full happy-path
flow (admin login, user create, upload, tag assign, tag filter, ACL
grant, pool create/add/reorder, trash/restore/permanent-delete, audit
log). Also add targeted tests for blocked-user login prevention, pool
reorder, and tag auto-rules. Uses a disposable postgres:16-alpine
container via testcontainers-go.
