refactor(prisma): consolidate migrations into single init files
Merge multiple incremental migrations into single init migration for each service:
- auth-service: 3 migrations → 1 (user auth, SMS, KYC)
- contribution-service: 4 migrations → 1 (contribution accounts, 15-level hierarchy, 3-tier bonus)
- mining-admin-service: 6 migrations → 1 (admin, CDC sync tables, prisma relation mode)
- mining-service: 1 migration (no change needed, renamed for consistency)
- mining-wallet-service: 3 migrations → 1 (wallet system, removed blockchain tables)
- trading-service: 1 migration (no change needed, renamed for consistency)
All migrations renamed from timestamp format (20260111000000_*) to sequential format (0001_init)
for cleaner migration history.
Note: Requires clearing _prisma_migrations table before applying to existing databases.
