Add new endpoint GET /api/v1/planting/stats/global to query planting
statistics directly from the database, providing reliable data source
for verifying reporting-service statistics.
New features:
- GlobalPlantingStats: total tree count, order count, amount
- StatusDistribution: breakdown by order status (PAID to MINING_ENABLED)
- TodayStats: daily statistics with tree count, order count, amount
Implementation:
- Pure additive changes, no modifications to existing code
- Read-only aggregate queries using Prisma aggregate/groupBy
- No database schema changes required
