test: add local Solana integration test with solana-test-validator

- Creates tests/solana_local.rs: transfers SOL, waits for slot advance, runs scanner
- Skips gracefully when validator not running (cargo test --all-targets safe)
- Uses --slots-per-epoch 64 for faster slot advancement
- Documents getBlock limitation on test validator vs real networks
