Blocked messages show exactly what to remove

When the gate blocks a message, the preview and block card now highlight every blocking span in your text and list each one as a chip with a Remove action, alongside Remove all and edit. A refused edit re-opens the edit box with the offending span already removed, so you can see and fix exactly what triggered the block instead of guessing.

Block explanations are now localized: a blocked message explains itself in German or French, not only English.

No action required.
