Native Apple Messages polls can have choices added after the poll is created. Those choices are stored in poll update rows, not necessarily in the original poll creation row.

Today imsg can expose poll.vote.option_id for those votes, but poll.vote.option_text may be missing when the selected option was added later and the vote row still points back to the original poll GUID.

Expected behavior:

• History and watch output should resolve poll.vote.option_text for original poll choices.
• They should also resolve poll.vote.option_text for choices added later through native Add Choice updates.
• Unknown or malformed update payloads should not break poll readback.
• Existing poll JSON fields should remain compatible.

This came out of follow-up review on native poll support after testing add-choice and vote flows against real Messages rows.
