The API returns {success: true, data: {...}} but code was accessing
progressResult.currentContributionPerTree directly instead of
progressResult.data.currentContributionPerTree.
This caused:
- totalTreeCount to be 0 (undefined → 0)
- networkTotalContribution to be 0
- No mining distributions happening

- Changed from reading config.remainingDistribution to calculating:
remainingDistribution = distributionPool - totalDistributed
- Ensures data consistency: remaining + distributed = total pool
- Added Math.max(0, ...) to prevent negative values

- Handle missing currentContributionPerTree with default value
- Add null checks for all network progress fields
- Prevent DecimalError when contribution service returns incomplete data

Previously used (pool - remaining) / pool which was incorrect.
Now uses actual distributed amount / total pool for accurate percentage.

- Add /api/v2/mining/progress endpoint in MiningController
- Update frontend API to call /progress instead of /admin/mining/status
- Kong routes /api/v2/mining/* with strip_path=false, so endpoint must
be under /mining controller path

- Wrap all database operations in executeSecondDistribution with
UnitOfWork.executeInTransaction
- Pass transaction client to repository save methods
- Use longer transaction timeout (60s) for batch operations
- Move Redis operations outside transaction (non-ACID)
- Add distributeToSystemAndPendingInTx method that accepts tx client
This resolves the "Unable to start a transaction in the given time"
error caused by multiple concurrent transactions competing for
database connections.

Prevent TypeError when config properties are undefined by using
optional chaining and default values in publishMiningConfigUpdated.

Add real-time mining progress statistics similar to burn progress:
- Backend: new /admin/mining/status endpoint in mining-service
- Frontend: MiningProgress component with progress bar and stats
- Shows: total distributed, remaining pool, minutes left, per-minute rate
- Auto-refresh every 60 seconds via React Query

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

The dashboard was incorrectly calculating distributed shares using
distributionPool - remainingDistribution. The correct value is the sum
of all users' totalMined balances. Updated mining-service to return
totalDistributed directly, and mining-admin-service to use it.

Add event publishing to enable mining-admin-service to sync data via
Debezium CDC instead of direct API calls:
- MiningConfigUpdated: Published every minute with distribution status
- DailyMiningStatCreated: Published when daily stats are generated
- MiningAccountUpdated: Method added for future per-account sync
These events will be captured by Debezium monitoring the outbox_events
table and forwarded to mining-admin-service via Kafka.

Mining-service incorrectly implemented its own burn mechanism (10-year
cycle) which was not in the requirements. Per requirements, only
trading-service should handle per-minute burn (4756.47/minute).
Removed:
- BlackHoleRepository and all burn-related methods
- executeBurn() from mining distribution service
- Burn stats from admin API and queries
- Burn progress UI from mining admin web

- Add UnallocatedContributionSyncedEvent in contribution-service
- Add event handler in mining-service's contribution-event.handler.ts
- Add handleUnallocatedContributionSynced in network-sync.service.ts
- Add admin endpoint to publish all unallocated contributions
- Sync pending/unallocated contributions to PendingContributionMining table

- mining-service: publish MINING_MINUTE_DISTRIBUTED event to Kafka after
each minute's mining distribution is completed
- mining-wallet-service: add MiningDistributionConsumer to consume the
event and deduct from SHARE_POOL_B
- Add deductFromSharePoolB method in PoolAccountService
- This ensures the share pool balance displayed in mining-app reflects
the actual remaining balance after mining distributions

All mining services need to read shared environment variables
(JWT_SECRET, DATABASE_URL, etc.) from backend/services/.env
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Backend changes:
- mining-wallet-service: Split SHARE_POOL into SHARE_POOL_A (100亿, for burning)
and SHARE_POOL_B (200万, for mining distribution)
- Add /pool-accounts/share-pool-balance API endpoint to get total balance
- Update pool initialization logic and seed data
- Fix Kong routing for mining-wallet-service (strip_path: true)
- Fix Kong routing for trading-service (strip_path: true)
Constant updates (100.02亿 = 10,002,000,000):
- mining-service: TOTAL_SHARES
- trading-service: TOTAL_SHARES, trading config defaults
- trading-service seed: initial green points = 5760
Frontend changes:
- Add sharePoolBalanceProvider to fetch pool balance from mining-wallet-service
- Update contribution page to display real-time share pool balance (A + B)

Add @Public() decorator to MiningController to allow mining-admin-service
to fetch mining records without authentication.

Changed event handler to:
- Listen to 'cdc.contribution.outbox' topic (CDC/Debezium format)
- Handle 'ContributionAccountUpdated' events instead of 'ContributionCalculated'
- Use effectiveContribution for mining power calculation
This fixes the issue where mining accounts had zero totalContribution
because they weren't receiving contribution sync events.

Add admin endpoints:
- GET /admin/status - Get mining system status
- POST /admin/initialize - Initialize mining config (one-time)
- POST /admin/activate - Activate mining distribution
Add prisma seed script for database initialization:
- MiningConfig: 100.02B total shares, 200万 distribution pool
- BlackHole: 100亿 burn target
- MiningEra: First era with 100万 distribution
- PoolAccounts: SHARE_POOL, BLACK_HOLE_POOL, CIRCULATION_POOL
Based on requirements:
- 第一个两年分配100万积分股
- 第二个两年分配50万积分股（减半）
- 100亿通过10年销毁到黑洞
