Merge origin/main: reconcile ConfigWindow consolidation with Debug window + protocol updates

origin/main (23 commits) added a Debug window/log system on top of the old
separate Devices/Channels/Plot windows, plus protocol fixes (cml, mark10,
modbus_rtu, scpi) and device/profile changes. Local main (3 commits)
replaced the separate windows with a unified ConfigWindow + dock panel.

Kept local's ConfigWindow/dock architecture and ported the Debug window
onto it: new toolbar button + _open_debug(), gated by developer_mode same
as origin's version. Deduped the two independent "developer mode" toggles
that had collided in SettingsWindow (origin's General-tab checkbox gating
Debug window + device sim-mode visibility, local's Advanced-tab checkbox
setting verbose logging) into one General-tab checkbox that does both.

+DEBUG window — developer-mode only.
+
+Minimal first pass: a live console showing everything the app has printed
+via core.debug_log (stdout/stderr tee), so debugging doesn't require a
+terminal. Not wired to any other diagnostics yet — extend as needed.
