Pull request overview
This PR adds validation to prevent users from configuring multiple controller replicas when using a local SQLite database, which would cause errors as API requests would be routed to replicas without the local state.
Key changes:
- Added a validation helper template that fails deployment when
controller.replicas > 1anddatabase.typeissqlite - Integrated the validation at the top of the controller deployment template
- Added comprehensive test coverage for both the failure case (replicas > 1 with sqlite) and the success case (replicas > 1 with postgres)
