- Introduce hepc-serve-global to serve global MRVA values from
hohnlab.org/mrva/values without local DB provisioning.
- Keep schema initialization symmetric across server and agent, while
serializing PostgreSQL DDL via a global advisory lock to prevent
concurrent CREATE TABLE races.
- Pin RabbitMQ image to rabbitmq:3.13.7-management to avoid credential
incompatibilities introduced by upstream image changes.
- Remove pre-hashed RabbitMQ credentials and return to deterministic
user/password initialization.
- Eliminate reliance on implicit container state to ensure reproducible
startup.
The primary purpose of this change is integration of global MRVA values;
the remaining fixes are required to make the new startup path reliable.
