redbear-ftdi/redbear-acmd: propagate USB setup errors + bump base submodule

redbear-ftdi: replace four silenced 'let _ = dev.{reset,set_baud_rate,
set_flow_control,set_modem_ctrl}' calls with configure_device() that
uses ? propagation. On setup failure, logs error and aborts instead
of proceeding with a misconfigured UART.

redbear-acmd: replace two silenced 'let _ = dev.{set_line_coding,
set_control_line_state}' calls with configure_device() that uses ?
propagation. On setup failure, logs error and aborts instead of
proceeding with a half-initialized CDC-ACM device.

Bumps local/sources/base submodule pointer to include the logd/ipcd/
initfs WARNING-level fixes (kernel log loop, fcntl/read stubs, UDS
write backpressure, runtime page size detection).
