Spawn protection shows warning messages, similar to beds

Similar to the messages that appear when a bed cannot be slept in (for instance, because it is too far away or because there are monsters nearby), or if you're trying to build at build height, a warning should appear when a player tries to interact with any blocks near world spawn that are protected, while they are not an operator. That way the player immediately gets feedback about why their interaction with that block failed.

With "interaction with a block" I mean breaking a block, placing a block, or using a block; basically anything that is prevented in the spawn area when you're not an operator.
