fix(webapp): don't allow toggling prod environment production status

[kaposke]

prod is a special environment that can't be renamed, deleted, and is always is_production = true. But the latter was not correctly reflected in the UI.

Disable prod Production Status Toggle in Environment Settings UI

This PR fixes a UI behavior in packages/webapp/src/pages/Environment/Settings/General.tsx so the special prod environment can no longer have its production status toggled. The production switch is now explicitly disabled when env === PROD_ENVIRONMENT_NAME, aligning frontend behavior with the existing rule that prod is always production.

It also improves UX by wrapping the switch in ConditionalTooltip to explain why the control is disabled for prod. Existing permission-based gating via PermissionGate and toggle confirmation flow remain in place for non-prod environments.
