[Bug]: Environment variables not passed & Frontend config not synced

Version: QwenPaw 1.1.12 (Docker)

Bug 1: Environment variables not passed to agents

After setting SUMMARIZE_WHEN_COMPACT=false via docker-compose environment, newly created agents still use the system default value true. The environment variable has no effect.

Bug 2: Frontend does not read local config

After modifying the model configuration in /home/ubuntu/copaw/secrets/providers, the frontend UI does not update and still displays the old model.

Bug 3: Attempting to upgrade to the untested v2.0 version directly caused a crash, making the service completely unavailable.

Steps to reproduce (Bug 1):

Add SUMMARIZE_WHEN_COMPACT=false to the environment section in docker-compose.yml.
Start the service and create a new agent.
Check the agent configuration – summarize_when_compact is still true.
Expected results:

Environment variables should override system defaults and apply to new agents.
The frontend UI should sync with the configuration file after a restart.
Version updates must be tested and must not break existing environments.
