Add Redis 7 to Docker Compose with healthcheck and persistence, separate logical DBs for blacklist and cache, singleton redis client helpers, and unit tests with fakeredis.
Foundational changes required before any new feature work can begin.
- 0.1 Redis infrastructure: add redis:7-alpine to docker-compose dev and prod,
REDIS_URL config, singleton client in app/infrastructure/redis_client.py

keyed by jti, auto-expiring TTL derived from token exp

for scoring, MTTD/MTTR, remediation, and notification queries
- 0.4 Domain exceptions TD-003: app/domain/exceptions.py with typed errors,
error_handler middleware mapping them to HTTP, services decoupled from FastAPI
- 0.5 Fix silenced exceptions TD-007: replace 4 bare except-pass blocks in
test_workflow_service with logger.warning with exc_info
- 0.6 CI pipeline TD-009: GitHub Actions workflow with Postgres and Redis
