Fix DAO method paths to match node implementation (#30)

Fixed 7 DAO method issues to match actual node endpoints:

1. getDaoTreasury: /treasury/balance → /treasury/status
   - Updated response parsing to treasury.total_balance

2. getTreasuryHistory: /treasury/history → /treasury/transactions
   - Added limit/offset query parameter support
   - Updated response parsing to transactions array

3. createProposal: /dao/proposals → /dao/proposal/create
   - Fixed singular 'proposal' path

4. getProposalDetails: /dao/proposals/{id} → /dao/proposal/{id}
   - Fixed singular 'proposal' path

5. submitVote: Updated request body format
   - Changed to voter_identity_id, proposal_id, vote_choice
   - Added support for yes/no/abstain and justification

6. registerDelegate: Fixed request body field names
   - Changed userDid → user_did
   - Changed delegateInfo → delegate_info

7. revokeDelegation: Fixed request body field name
   - Changed userDid → user_did

All paths now match node's dao/mod.rs implementation (lines 957-1029)
