Extract governance domain models to governance-service

- Created domain directory with governance models
- Extracted governance domain models from coordinator-api:
  - ProposalStatus, VoteType, GovernanceRole enums
  - GovernanceProfile
  - Proposal
  - Vote
  - DaoTreasury
  - TransparencyReport
- Updated domain __init__.py to export all models

This completes Phase 4.6b: Extract governance domain models
