feat(modules): wire registry into server startup

Add modules.Registry and config.Config fields to Server struct.
Create registry in main.go, load state from YAML+DB, log all
module states at startup.

Conditionally start job/runner sweeper goroutines only when the
jobs module is enabled.

Update all 5 test files to pass registry to NewServer.
