Public tags: protocol tag for transaction list

[tom2drum]

Description and Related Issue(s)

Resolves #2976

This PR adds support for displaying protocol tags in transaction lists, similar to the functionality implemented in issue #2912. Protocol tags are now shown in transaction list views to help users quickly identify protocol-related transactions.

Proposed Changes

• Added protocol tag display in transaction list components:
  • Table view: Protocol tag appears in the Method column below the method name (when a method is present)
  • List/Mobile views: Protocol tag appears alongside other transaction tags (type, status, watchlist tags)
• Updated transaction list components to extract and display protocol tags from tx.to?.metadata?.tags where tagType === 'protocol'
• Added protocol tag support to LatestTxsItem, TxsListItem, and TxsTableItem components
• Updated mocks to include protocol tag data for testing
• Updated Playwright test snapshots to reflect the new UI changes

Breaking or Incompatible Changes

None.

Additional Information

The implementation follows the design specified in issue #2976, where protocol tags are displayed in the Method column below the method name for table views. In list and mobile views, protocol tags appear alongside other transaction tags for consistency with the existing tag display pattern.
