When a managed variable shares a Compose-defined key, show the
hardcoded Compose value as read-only and exclude it from managed
rows. Render Contact support as a button, use the collapsible
component for 419 proxy help, and style its list/code markers.
Surface unset required service env vars in the configuration checker
popup and sidebar, refresh on env updates, and keep the env table
horizontally scrollable with correct managed/hardcoded pagination order.
Search environment variables case-insensitively by key, add accessible search
labeling, and ensure switching to developer view after searching loads the full
variable set so non-matching entries are not removed on save.
