Add new POST endpoint and update profileId type to long

Added a new HTTP POST endpoint `invoke/fake` in `RecActionController`
to invoke batch actions with a fake profile ID. Updated the `profileId`
parameter type in the `InvokeBatchRecAction` extension method from
`int` to `long` to support larger profile IDs. These changes improve
flexibility and introduce a new endpoint for specific use cases.
