Ability to deactivate or hide a category that is no longer in use

The goal would be to "hide" or "deactivate" categories so that they no longer show up in the list of categories available to add to new transactions, but without deleting them completely so that old transactions with those categories can keep them.

An example would be I have a wedding category, and we got married and so it's no longer relevant, but the algorithm still tries to auto categorize things to that category. So I have to manually fix it.
