Type safe allow and disallow

[DamianKocjan]

Closes #1099

Description

This PR introduces type safety for the allow and disallow props within Puck's Slot/DropZone.

Changes made

Updated DropZoneProps to use the generic component type for allow and disallow arrays.

How to test

Open a component configuration in a TypeScript environment (e.g., apps/demo/config/blocks/Flex/index.tsx).

Ensure the component is typed using the new generic: ComponentConfig<Props, keyof Components>.

Inside the render function, find a Slot.

Try to add an allow prop:

<Slot allow={["NonExistentComponent"]} /> 

Verify: TypeScript should throw an error because "NonExistentComponent" is not a key in your Components type.

Verify: Triggering autocomplete within the allow array should suggest valid component names from your config.
