refactor(push): clean up legacy push_config and w_push_events hardcoded insertions

- Remove ConfigKeyPushConfig and delete legacy push_config query logic from EventTrigger.Trigger.
- Simplify the push event notification dispatching engine to rely purely on database custom channels.
- Remove w_push_events hardcoded INSERT statement from migration files, letting SyncEvents handle default event registration.
- Rewrite unit tests to use model.PushChannel instead of push_config.
