Handle txs that execute a multisig tx and transfer NFTs

**Current Behavior**
There is no caption for posts that involve a transaction that:
1. Originates from a profile
2. Executes a multisig tx
3. Transfers an NFT from the multisig to a third party

**Expected Behavior**
Figure out how to display/what to caption these txs.

No files or tests are identified in the issue. Start by tracing how captions are generated for profile-originated transactions, then follow the multisig execution and NFT transfer handling; done means these transactions produce an appropriate caption.
