Problem:
- Multiple concurrent transactions updating system_mining_accounts caused row lock contention
- 16+ transactions waiting for tuple/transactionid locks led to timeout errors
- This prevented writeMinuteRecords() from executing, leaving mining_records empty
Solution:
- Modified SystemMiningAccountRepository.mine() to accept optional external transaction client
- Created new distributeToSystemAndPending() method that processes all system accounts
and pending contributions in a single transaction
- Pre-calculate all rewards before transaction, then execute updates sequentially
- Aggregate all pending contribution rewards into single HEADQUARTERS update
- Move Redis accumulation outside transaction to avoid blocking
