Add best painted and most sporting polls

[ianpaschal]

User Story

As a TO: I want to run polls for best painted and most sporting. I want players to be able to vote via the app so that I don't have to mess around with lots of paper slips. I still want the ability to make the final choice though so that I can factor in other elements (perhaps the would-be-winner won the same prize last year, want to give it to someone else, etc.)

Functional Requirements

• The TO can open a poll at a time of their choosing.
• The TO can close an open poll at a time of their choosing.
• If a poll is opened, email users to remind them to vote.
• The TO can see the status of the vote at any time.
• The TO can click the "Award" button on the vote status.
  • This will close the vote.
  • This should show a warning if some votes are not in.
  • This creates a new TournamentAward record for that competitor.

Implementation Details

This should be a separate entity in the DB; probably a TournamentPoll. By default it contains all competitors as options and each competitor can vote once.

Although this maybe should also incorporate a TournamentPollVote and they're all linked to one poll, this might be over-engineering it and meaning that to get the results you have to read 20-50 documents instead of 1. Instead a TournamentPoll schema could look like:

const fields = v.object({
  isOpen: v.boolean(),
  winnerTournamentCompetitorId: v.optional(v.id('tournamentCompetitors')),
  votes: v.array(v.object({
    castByUserId: v.id('users'), // Or registration ID?
    castForTournamentCompetitorId: v.id('tournamentCompetitors'),
  }),
});

This will actually not be dependent on #244 so it is unblocked. To avoid awards "leaking" onto players' profiles before a tournament is actually over, awards will be applied when a tournament is ended.
