Add Azurite to test infrastructure (#36485)

Wire Microsoft's local Azure Blob Storage emulator into the dev/CI
docker-compose stack so an upcoming Azure FileBackend driver and its
tests have a target to run against, without requiring an Azure
account.

* Define the azurite service in docker-compose.common.yml (used by
  both the local-dev and CI compose files).
* Add azurite to the makefile + main docker-compose.yml service maps,
  and to docker-compose-generator so callers can include it via
  ENABLED_DOCKER_SERVICES.
* Auto-include azurite in `make start-docker` (mirrors how minio is
  auto-included today), so existing local workflows keep working
  without any per-developer config change.
* Add azurite to the CI start_dependencies wait set so CI brings it up
  alongside postgres/minio.
* Set CI_AZURITE_HOST / CI_AZURITE_PORT in dotenv/test.env, mirroring
  the CI_MINIO_* pattern.

No production filestore changes — this PR is mergeable in isolation
with no user-visible behavior.
