Abstimmung: mehrere Agenten pruefen unabhaengig und stimmen blind ab (#702)

A unit can put operations to a blind vote instead of its lead. Not opinions
are counted but independent checks enforced.

- UnitConfig.votes: operations, voters, approveAt, rejectAt, quorum, hours,
  perDay - set only by a human (OrgAdministration.SetVotes).
- Core/Staging/Votes: routes a covered staged call before the lead; one task
  per voter with the frozen call and nothing else; cast_vote needs reasoning
  and evidence. Counted as soon as the result is settled; in between and
  without the quorum a human decides. The proposer does not vote, voters that
  read foreign content get no ballot, changes to agents never go to a vote.
- Escalation tool: list_ballots, cast_vote.
- Approvals view shows each vote with every ballot and the voters' costs;
  organisation view sets the rule and lists the votes held.
