find-or-reuse-a-poll

Finds one of the user's existing CrowdHum polls or sessions and helps reuse it. Use when the user asks "what's my room code for <X>", "find my poll about <Y>", "re-run last week's poll", "reuse the icebreaker from Monday's standup", "open my <event> session again", or wants to look up, resume, or clone a poll they already made. Locates it, returns the links, and can recreate a fresh copy.
