fix(agent): correct async provider switching and settings resolution

Convert setProvider to async method and update all callers to properly await.
Fix settings manager mock to merge user and project provider configurations
correctly and handle case-insensitive provider IDs. Remove debug console
logging from setProvider. Update unit and integration tests to handle async
provider switching.
