test: add 4 new unit test suites for mining modulesfeature/mining-payment

- test_stratum_proxy: job set/get, stats, init (21 tests)
- test_session_payment_method: PAYMENT_METHOD enum, bytes/cashu methods (12 tests)
- test_tollgate_client_mining: mining tag parsing, discovery struct (20 tests)
- test_firewall_sandbox: client management, grant/revoke, max clients (16 tests)
- Enhanced stubs: BaseType_t/pdPASS in task.h, lwip sockets/etharp/prot headers,
  dns_server.h, esp_wifi_ap_get_sta_list.h
- All 15 test suites pass (344+ total assertions)
