Delete Bulk Message history

Observation: Currently, clearing message history is a slow, one-by-one process. I have to delete a single message, wait for a confirmation pop-up, confirm, and then repeat. For someone with a long history, this is extremely time-consuming.

• Suggested Improvement:
  "Select All" Checkbox: Add a checkbox system to the message list so I can select multiple (or all) messages at once.

• Bulk Delete Button: A single "Delete Selected" button that uses one confirmation prompt for the entire batch.

Why this helps: It streamlines account maintenance and keeps the inbox from feeling cluttered. Most users expect to be able to "clean house" in a few clicks rather than dozens.
