Matysh 09b0ba41a5 fix v1.44.4: audit follow-up B2, B5, L4 sub-item
B2: the HTTP upload view failed OPEN when the config entry was
unavailable while the WS path failed closed — both now share one
may_write() policy helper (new auth.py) that denies non-admins when the
policy cannot be read.

B5: _finite now guards room rects, polygon vertices, view_box and
opening coordinates, not just layout positions; the declared
MAX_OPENINGS cap is finally enforced.

L4 (sub-item): every drag pipeline captures the pointer through the
tolerant helper (an inactive pointerId used to kill device/label/resize
drags); decor shapes gained a bounds clamp so they cannot be dragged far
outside the plan and persisted there.

+2 backend tests (16); both changelogs updated in this commit

"""Single source of truth for the write-authorization policy.
The WS and HTTP paths used to duplicate this decision and drifted apart: the
WS copy was fixed to fail closed while the upload view still failed OPEN when
the config entry was unavailable (audit follow-up B2, 2026-07-27). One helper,
one behaviour.
