fix: disable address normalization when checking blocked MMS senders (#644)

Removed MMS sender address normalization when checking against blocked numbers. Previously, blocking an alphanumeric address such as `VE-ViCARE` would block MMS messages from `VE-ViCARE` and the normalized number `83842273`. Even if that collision never occurs in the real world, removing normalization is the correct move and is consistent with how SMS blocking works.
