fix(bec_widgets): warn before "Add current params to queue" during an edit

Real footgun: edit a value in the params panel but don't click its own
"Add to queue" (or Submit) -- then use the *separate* Queue control
window's "Add current params to queue" button, expecting it to queue
what was just typed. It doesn't: that button reads live global vars
(TOMO_QUEUE_COMMAND_JOBS_PLAN.md section 6.1's rule -- only the panel's
own Add-to-queue reads the form), so it silently queues the stale,
pre-edit values with no indication anything's off. Now checks the
parent params panel's edit-mode state and, if an edit is in progress,
warns explicitly and points at the correct button before proceeding
-- a warning rather than a hard block, since queuing the live params
alongside an unrelated in-progress edit elsewhere is still a
legitimate thing to want.
