feat: add Solana payment scanning with USDT/USDC support and wallet management API

- Rewrite Solana scanner: stateless scan with processed-signature cache, query wallet + USDT ATA + USDC ATA addresses to cover all SPL transfers
  - Add network field to transaction_lock (4-tuple unique index) and order flow
  - Add wallet management endpoints (add/list/get/status/delete) with token auth
  - Add network info to Telegram payment notification
  - Add USDC hint to test script GMPay prompt
  - Add API docs and Solana scanning docs
