Feature: Events for yield distribution (to be indexed on frontend)

[RonTuretzky]

Events for each bread distribution should include voters for each project, distribution percentage

• [x] Vote distribution percentage for each project
• [x] base amount distributed for each project
• [x] Voted amount distributed for each project
• [x] Voters for each project

@subject026 please add more if there are any others?

[RonTuretzky]

@subject026 Would appreciate your review for the PR , and if it meets the frontend requirements

[RonTuretzky]

New requirements:

- [ ] Condense the distribution event to one event as listed here https://github.com/BreadchainCoop/breadchain/pull/27#discussion_r1581008906

• [x] Remove summation of voters
• [x] Introduce event for single vote

[RonTuretzky]

Not condensing event for indexing utility
