fix: build errors in cvm_server, stratum_proxy, sw_miner + nucula visibility

- cvm_server: replace esp_timer_get_time() with xTaskGetTickCount(), fix
  process_relay_message() call signature (3 args -> 2)
- stratum_proxy: widen task_name buffer from 16 to 20 chars
- sw_miner: add missing #include esp_random.h
- nucula_src: save_proofs() moved to public in wallet.hpp
- CMakeLists: ensure tcp_transport in REQUIRES
- tollgate_main: add display.h, local_relay.h, relay_selector.h, sync_manager.h includes
- Build now succeeds: 1.2MB binary, 70% partition free
