Detailed Description

CAPI UART external-loopback tests.

Exercises the CAPI UART API on ONE controller wired in EXTERNAL loopback: its TX pin is physically strapped to its own RX pin on the board. Internal (local) loopback is deliberately NOT used – line_config.loopback stays false – so every case moves real bytes over a real wire and back.

This is a second, spare UART, never the console: the framework's report transport is a different instance entirely (uart_config), and reconfiguring that one mid-run would silence the log.

Hardware assumption: one UART with TX looped back to RX externally.
