config(teslamate): Remove Docker secrets for sensitive values

Replaced Docker secrets with direct environment variable assignments for `ENCRYPTION_KEY`, `DATABASE_PASS`, and `POSTGRES_PASSWORD` in the `docker-compose.yml` file.

This change simplifies the deployment by removing the dependency on Docker secrets for these values, opting for hardcoded strings instead. The `secrets` section has been removed from all relevant services (teslamate, database, grafana, mosquitto).
