fix(contribution): only publish adoptions with contributionDistributed=true

When publishing adoption events to mining-admin-service:
- Only include adoptions where contributionDistributed=true (already processed)
- Force status to 'MINING_ENABLED' since these are active adoptions

This ensures mining-admin-service only counts valid, processed adoptions.
