Add Input Mapping

Bind a key to an Input Action inside a mapping context, and verify it by reading the context's live mapping list back. Goes through the engine's own MapKey, so it lands wherever this engine version keeps mappings. That matters: the array moved in 5.7 and a generic property write to the old name still succeeds, still reads back, and does nothing.

Arguments

Name	Type	Description
`action`req	string	Path of the Input Action to bind.
`context`req	string	Path of the Input Mapping Context to add to.
`key`req	string	Key name as the engine spells it: W, SpaceBar, LeftMouseButton, Gamepad_LeftX, Gamepad_FaceButton_Bottom. An unknown name is refused rather than bound to nothing.
`force`	boolean = false	Edit even when the asset cannot currently be saved - for example when revision control is configured but disconnected. The change will be made in memory and WILL BE LOST unless the underlying problem is fixed before saving. Only pass this if you intend to discard the work or fix the connection first.
