feat: open-source worker group configuration UI (#7954)

* feat: gate private registry configuration behind enterprise feature

Add read_ee_registry<T> helper that returns None and emits a job log
in CE builds when a private registry is configured. Applied to all
language executors: pip, npm/bun, deno, cargo, go, maven, nuget,
powershell, and ruby. Maven settings.xml file write in monitor.rs
is also gated.

* feat: open-source worker group configuration UI

Allow CE users to create worker group configs and edit worker_tags.
EE-only features (dedicated workers, custom env vars, init/periodic
scripts, autoscaling, priority tags, etc.) remain gated behind the
enterprise license in the UI. Backend now filters CE config updates
to only allow worker_tags and cache_clear fields instead of rejecting
the entire request.
