The acknowledged overhang: "doesn't fit, shelved anyway" goes legit

Eric's office towers are 9.5 inches deep; Etherfields boxes are 11.8
inches square. Spine-out they stand 2.3 inches proud of the shelf edge
— clearly livable, it's how they sit today — but the lane model will
honestly refuse forever: can't stand (11.8 > 9.5 depth), can't stack
flat (same), so the opening warns NO PACKING FITS. The first deliberate
misfit deserves first-class status.

An assignment can now carry acknowledged: true. An acknowledged box
takes the standing lane WITHOUT the height/depth check — the human has
seen the overhang — while the width budget stays honest (nine
acknowledged monoliths still overflow a 23.25-inch row). It drops out
of misfit/laneless warnings everywhere: the wall diagram, the sheet,
and bggpipe dims (which now says "overhangs, acknowledged" instead).

Ways in: an "accept overhang" button in the opening's sheet (appears
on any resident the lanes can't take; tap again to retract), or an
acknowledge column (yes) in shelve --import. Once acknowledged, later
imports needn't re-state it.

Re-import hardening, prompted by Eric's "will a new import make a
mess?": it's an upsert, not a reset — and now genuinely so. Previously
a re-import preserved notes but silently wiped lane overrides; now
notes, lanes, and acknowledgments all survive when the opening is
unchanged (a move resets lane and acknowledgment — new spot, new
verdict). Same fix in /api/locate: the lane-flip button used to wipe
the hand-entered note because LocateBody.note defaulted to "" —
it's now tri-state, None means leave it alone.
