ci(devx): run the platform-checklist gate's own self-test through its alias

`check:self-test-wired` reds the moment CI runs a script that ships a
`--self-test` no workflow executes — and the watchdog makes CI run this one.
Wiring the flag into the root alias is the remedy that gate names; a
SELF_TEST_RUN_OTHERWISE row would be the finding written down somewhere quieter.

The gate's header said a `--self-test` leg here "would execute NOWHERE". That
premise is falsified by the watchdog, so the header is corrected rather than
left to read as verified. The inline battery stays inline.
