Clean up and consolidate escalation module

Remove dead code:
- Delete simpleVote.ts and majorityVote.ts (replaced by Effect handlers)
- Delete old escalationVotes.server.ts model (replaced by EscalationService)
- Remove unused vote handler from voting.ts (keep pure functions only)

Consolidate types and imports:
- Export Escalation/EscalationRecord types from EscalationService
- Move calculateScheduledFor to helpers/escalationVotes.ts
- Update all imports to use new locations

Files modified: 9 (cleanup and import updates)
