P2 Badge Pass the TLS toggle into Docker Compose services

When a self-hosted operator copies .env.example and sets this to false, the provided Compose deployments still won't pass it into the containers: the blob-storage environment blocks in docker-compose.yml enumerate the endpoint and bucket vars but omit this new key (e.g. lines 78-84, 156-162, 237-243, 306-312, and 428-434). Since Compose .env values are only used for interpolation unless listed in a service environment block, tracecat/config.py falls back to true and the new TLS-disabling option has no effect in the documented Docker Compose path. Please thread ${TRACECAT__BLOB_STORAGE_SSL_VERIFY:-true} through each service that talks to blob storage.
