Dispatch an Event when a value was changed

[blizzz]

Is your feature request related to a problem? Please describe.

When a cell value was changed, a typed event shall be dispatched. The Event shall be JSON-serializable.

Describe the solution you'd like

The event shall be emitted as normally per EventDispatcher.

The Event should contain the information:

• acting User
• affected Table
• affected Row
• affected Column
• affected Cell
• old value
• new value

The Event shall be JSON-serializable. The objects will be slimmed down to their IDs in that case.

Describe alternatives you've considered

No response

Additional context

This is required for the upcoming workflow engine efforts.

@blizzz Could you line up picking up the PR from @come-nc to move this forward?

@blizzz Please also take care of having an event for row created here (or have this covered also in the changed event)
