Community Validator output on worker

[steinerkelvin]

We need to add to the long-lived worker service:

• Gets user votes from DB, calculates final weights and sends to blockchain
• Make available vote data to frontend

[steinerkelvin]

• [ ] asserts on final weight function test
• [x] query user stakes from blockchain
• [x] query modules user votes/weights from DB
• [ ] have module's uids on db
• [ ] think about how to serve back to frontend
