v1.46.2: re-check of v1.46.1 — HP-1461-01, -02

HP-1461-01: collection was tied to config/set, which is the right scope for
what a commit supersedes but leaves a file nobody references with no future
write to notice it — cancel a dialog after the upload finished, drop the
connection just after, or call the upload API directly. The daily sweep added
in v1.46.1 only removed streaming temporaries, so the documented 'a cancelled
attachment is collected an hour later' did not hold on an instance nobody
edits. The scheduled pass now loads the stored config under the same write_lock
a commit uses and runs collect_attachments/collect_plans with it as BOTH sides:
nothing counts as superseded, referenced files are preserved, aged unreferenced
ones go. Doing it under the lock keeps it from deciding on a snapshot a commit
is about to replace.

HP-1461-02: _reloadLayoutOnly captured the dirty set AFTER flushing the pending
write, and the flush empties it first — so during a real drag (where a write is
already scheduled) the snapshot was empty and the server's older position was
merged over the user's move. The snapshot is taken before the flush, by value,
and a _sentPos map now holds positions that are sent but unacknowledged, which
closes the same window for a write that was already in flight.

Tests: the upload test now cancels the request task for real (the previous one
claimed to and only walked error paths); smoke_layout_sync schedules a genuine
debounced write and delays it — verified failing on a v1.46.1 build with
exactly the reported symptom; a new backend test reloads the entry and asserts
the scheduled sweep takes an aged cancelled attachment and an orphan plan while
keeping everything the config still references.

+| Version | **v1.46.2** everywhere (manifest, const.py, package.json, CARD_VERSION); deployed to the home instance |
 | Workflow | Since 2026-07-22: minor changes go to branch **`dev`** (build + smokes → deploy home → commit → push, NO release); releases are batched on the owner's command (merge dev→main, one tag, one release with a summary changelog, CI checked on dev beforehand) |
 | GitHub | https://github.com/Matysh/houseplan-card — **`main` carries every published release, the latest tag is the current version above**; `dev` is where work lands and is merged into `main` at release time (so `dev` is normally equal to or ahead of `main`, never behind). Push via SSH key `ha_jb` (remote git@github.com:…); API releases via the fine-grained PAT in `~/.git-credentials` (Contents R/W, issued 2026-07-23) |
 | CI | validate.yml (hacs + hassfest + frontend + backend) green; release.yml attaches the bundle on release publish |
 | HACS | Custom repository works. **Inclusion PR: hacs/default#9004** — open, valid, labeled; ~864 older open PRs but merge rate ≈180/mo; realistic ETA 1–3 months (checked 2026-07-24) |

 | Localization | UI en/ru (src/i18n/*.json), everything user-visible localized incl. kiosk popover |
 | Tests | Four layers: frontend unit (`npm test`, node:test over `test-build/`), pure backend (`pytest tests_backend`, runs anywhere), HA-harness backend (same folder, CI only — needs py3.13 + pytest-homeassistant-custom-component), and browser smokes (`demo/smoke_*.mjs`, headless chromium). **Counts are not written down here** — they went stale within two releases while the version line beside them was kept current, which reads as less coverage than exists (review R5-2). Run `npm run inventory` for the current numbers, or read them off the last CI run |
