Hotseat setup round: pick a count, then each wizard names themselves

The comma-separated name field is gone. Hotseat now starts with a
2-6 count picker and "Gather N wizards", which opens a naming round
in the pass-the-device style: "Wizard 1 of 3 — what is your name?",
type it, pass the device on; the last wizard's button reads "Flip the
boards" and starts the game. Duplicate and empty names are refused
in place, the roster-so-far shows beneath, and "never mind" backs
out. Verified end to end: three names entered, game started, opening
handoff went to the die-roll winner.
