v1.46.0: full external audit of v1.45.4 — HP-1454-01 … -10

HP-1454-01 (high, release blocker): an uploaded SVG plan opened directly is a
top-level document of Home Assistant's own origin, so a <script> inside it
reaches the session's localStorage and API. Uploading needs write access, which
by default every authenticated user has. SVG responses now carry a sandbox CSP;
only SVG, because a CSP on a PDF can break the browser's viewer and a raster
image has nothing to disable. Verified in Chromium both ways: the script runs
without the header and does not with it.

HP-1454-02: attachment uploads wrote straight to <marker>/<filename>, outside
the config transaction — a cancelled dialog or a rejected save left the stored
url serving new bytes, and every new icon shared one 'new' folder, so two of
them attaching manual.pdf pointed at one file. Uploads take a free name, a new
icon gets a per-dialog staging folder promoted on an accepted save, and
config/set collects superseded and aged-orphan attachments like it does plans.

HP-1454-03: the debounce spaced out the starts of a write, not the writes. A
save slower than 500 ms let the next edit go out with the same expected_rev;
the server accepted the first, rejected the second, and the conflict handler
reloaded over the local copy. Writes are chained now — one in flight, each with
the revision the previous returned.

HP-1454-04: _openPairsCache keyed on room ids and links only, so an aspect
change or a dragged vertex left open boundaries and their glow cuts at old
coordinates. It keys on the rendered model object now — the same invalidation
the model cache already has, not a second strategy. The fingerprint also gained
an O(1) geometry roll-up per room.

HP-1454-05: outer collections were capped, inner ones were not. Limits for
poly points, open_to, controls, pdfs, text and url lengths, plus a total
serialized size cap; legacy  is dropped server-side.

HP-1454-06: upload streams to a temp file and downloads use FileResponse, so a
50 MB manual no longer costs ~100 MB of RSS per transfer.

HP-1454-07: spaceModels() dropped room.settings, so the static card ignored the
per-room fill override. HP-1454-08: layout had no revision on point-wise writes
and no event, leaving static cards stale forever; it now keeps a revision,
returns it and fires houseplan_layout_updated. HP-1454-09: repair cleanup only
walked existing spaces, so a deleted space kept its warning. HP-1454-10:
serialize-javascript pinned past two advisories.

Tests: smoke_svg_sandbox (proves both directions), smoke_config_writer and
smoke_render_parity (both verified failing against a v1.45.4 build), six pure
tests for attachment collection and inner limits, four HA-harness tests for the
CSP, non-overwriting uploads, the size cap and layout revisions.
