fix(contribution-service): filter adoptions by MINING_ENABLED status

Only process adoptions with MINING_ENABLED status for contribution calculation.
This fixes the bug where non-final adoption records (PENDING, PAID, etc.) were
incorrectly being processed, causing duplicate contribution records.

Affected methods:
- findUndistributedAdoptions: only process MINING_ENABLED adoptions
- getDirectReferralAdoptedCount: only count users with MINING_ENABLED adoptions
- getTotalTreesByAccountSequence: only sum trees from MINING_ENABLED adoptions
- getTeamTreesByLevel: only count MINING_ENABLED adoptions
- countUndistributedAdoptions: only count MINING_ENABLED adoptions
