Parse an explicit IN:OUT console-size pin (e.g. 4:2) — rig.console in the
config, historically OPENMIXER_CONSOLE. Returns undefined when unset; a
set-but-malformed value is logged and ignored (falling back to detection) rather
than silently shrinking the console to 0:0 — a config typo must not refuse to boot.
