fix: resolve container startup race condition in agents service (#451) (#503)

* depends on and env var added

Update Vite configuration to enable allowed hosts

- Uncommented the allowedHosts configuration to allow for dynamic host settings based on environment variables.
- This change enhances flexibility for different deployment environments while maintaining the default localhost and specific domain access.

Needs testing to confirm proper functionality with various host configurations.

* Enhance Vite configuration with dynamic allowed hosts support

- Added VITE_ALLOWED_HOSTS environment variable to .env.example and docker-compose.yml for flexible host configuration.
- Updated Vite config to dynamically set allowed hosts, incorporating defaults and custom values from the environment variable.
- This change improves deployment flexibility while maintaining security by defaulting to localhost and specific domains.

Needs testing to confirm proper functionality with various host configurations.

* refactor: remove unnecessary dependency on archon-agents in docker-compose.yml

- Removed the dependency condition for archon-agents from the archon-mcp service to streamline the startup process.
- This change simplifies the service configuration and reduces potential startup issues related to agent service health checks.

Needs testing to ensure that the application functions correctly without the archon-agents dependency.
