SDD workshop: run-through fixes (2026-10-15) #342

Live fixes from Avi's run-through of the SDD workshop flow, 2026-10-15. One branch, one PR.

• 1. Timer too big: projector screen + player phone
• 2. Loading states bad on facilitator view + player view
• 3. Pairing must work with only 2 players
• 4. Odd player can pair with a facilitator
• 5. Projector + player pages don't match current design (host app is fine, it's the reference)
• 6. Voice off → confirm screen drops the voice-only buttons
• 7. Projector shows more than the QR: how to play, round + clock, counts, join URL
• 8. Pair by typing partner's name, not just their code
• 9. Thumb up/down own question after answering (needs migration 0005 on prod before deploy)
• 10. Optional manual "revisit your questions" email after the workshop, opt-in players only
• 11. Round option: physical cards (phones show no question, rest of the game unchanged)
• 12. Delete or copy a workshop, any status incl. ended
• 13. Projector mode with host controls on the same screen: how to join, how the round works, start/end round etc. (no switching screens)
• 14. Voice answers transcribe + save in the background; no review screen mid-game, players see/edit after in My answers

PR: #343 🔀. Round of edits closed after 14.
