noframe: drop the drag-by-surface -- it is a finishing step, not a mode

Browse Source 
Author's correction to the shape of yesterday's option.  The intended workflow
is: place the displays where you want them WITH their frames, quit, then edit
glass_layout.cfg to turn the frame off.  So a ,noframe window should be pinned,
not draggable -- removed the WM_NCHITTEST -> HTCAPTION handler that made the
surface a drag handle.

The arrangement being finished is the point: with no caption there is nothing
to drag it by, which is exactly what you want on a wall of monitors.  Delete
the flag to get the frame (and the dragging) back.

Unchanged and still needed: SaveLayout writes the flag back, because any later
drag of a FRAMED window rewrites the whole file and would otherwise strip it.

Re-verified live:
 - Heat MFD comes up with WS_CAPTION clear and answers WM_NCHITTEST on its
   surface with HTCLIENT (pinned) -- no window reports HTCAPTION any more.
 - Comm MFD (unflagged) keeps its caption.
 - A framed window's WM_EXITSIZEMOVE rewrote the file and BOTH ,noframe flags
   survived, with the new header explaining the arrange-first workflow.
 - surround / exploded / pod / dev boot and simulate clean.

Docs updated to describe the two-stage workflow rather than surface dragging:
the file's own header, environ.ini's BT_GLASS_LAYOUT block, context/
glass-cockpit.md and the ledger (which records the removed behaviour so the
next reader does not re-add it).
