refactor(thumbnails): keep the after-scan queue's store rule and pin the write lock (#320)

A planned target keeps the plan's own containment rule (inside the
store, as the thumbnail job writes it); captures keep the serve rule.
The structural test also covers PREVIEW_FOLDER joins and the
repo-root modules; the write-lock test asserts the lock instead of
waiting on a timer; new tests cover nested roots in the after-scan
queue and a legacy upper-case preview served through the resolver.

-saved, from their saved pairs. It is reviewed and applied like the operations above and
-follows the safety backup policy like them (no forced backup). Rules
-(`docs/egm/post-3.4.1/550-design.md`):
-
-- Considered: prompts the Pair node created as a positive: their earliest pair (lowest
-  id, either role, archived included) has them as the positive and its `created_at` is
-  within 2 s of theirs. A prompt first saved by the PromptManager node, or first as a
-  negative, is out of scope and not counted.
-- Sources: the prompt's non-archived pairs where it is the positive; pairs with a blank
-  category or no tags are ignored for that field. Category values are trimmed and
-  case-sensitive, tag sets compared by tag id; a field fills when exactly one value is
-  left. A whitespace-only category counts as empty.
-- Kept, per field, in this order: archived prompt, edited prompt (`updated_at` not within
-  2 s of `created_at`; NULL or unreadable counts as edited), pairs that disagree, a tag
-  set over 20 tags. A prompt can fill one field and keep the other.
-- The plan lists protected rows first, then fills, then a "Record" row, within the 50
-  detail rows; at most 20,000 prompts per plan ("review again for the rest").
-- The fingerprint covers each considered prompt's computed result (values, tag ids and
-  names, source pair ids), never a pair's title, notes, rating, run count or use
-  stamps, so a Pair run between review and apply still applies.
-- The apply's writes are guarded (`category` still blank, no `prompt_tags` row) and a
-  guard that hits nothing rolls the whole transaction back as `plan-changed`. It never
-  writes `prompt_pairs`, `prompt_pair_tags`, `updated_at`, a tag or Library state.
-- The job lists 200 changed rows ("Prompt 12: category “night”; tags a, b"); its
-  Download report lists every one (`truncated: false`, `Job.record_counted(complete=True)`).
-  Protected lists one row per kept prompt in the review's wording and order ("Prompt 7:
-  kept, pairs disagree on category: Adult, asian"), also complete in the report.
-- Activity shows a row with no path as a record: its detail as plain text, never an open
-  or locate action, and the filter reads the detail. A maintenance job of records (every
-  operation but Missing-file links) says "No records in this group.", "No listed record
-  matches this filter." and "Filter records…" (`groupCopy`); file jobs keep "files".

-### Thumbnail location contract (#320)
-
-Previews live in each source's `thumbnails/` (the default) or in one folder, `<folder>/<source key>/…`. Every reader,
-writer and remover asks `py/api/preview_store.py`; `tests/test_preview_store.py` fails on a `thumbnails` path join
-anywhere else. The setting is `thumbnails.location` in config.json, and only the Move thumbnails job writes it: POST
-`/settings` answers 409 `location-needs-move`.
-
-- **Keys and marker.** A key is a slug plus a hash of the source's identity. The folder's
-  `.promptmanager-thumbnails.json` stores each key with its identity and install. Only a single `<slug>-<hex>` name
-  is ever joined onto the folder, and anything else in a marker is dropped. Every write and delete passes
-  `preview_store.may_write`: below a key folder, with no link, junction or reparse point on the way
-  (`tests/test_preview_store_folder.py`, including tampered markers).
-- **Unavailable.** A folder is unavailable when it is missing, is a link, holds no marker or holds another
-  folder's marker. A probe checks it every 5 s, and a store call that fails or stalls marks it at once. While it is
-  unavailable:
-  - originals are served and nothing is written anywhere;
-  - generate, convert, clear and prune answer 409 `location-unavailable`;
-  - the folder is never made again except by Recreate folder.
-
-  The configured location is in force before any request. A bad value is `invalid`, never a fall-back to the
-  sources.
-- **Move thumbnails.** The job is a `thumbnails` job with `scope.mode` `move` (`tests/test_thumbnail_move.py`). It
-  runs in this order:
-  1. The review answers `POST /images/thumbnails/plan`; not enough space answers 507.
-  2. A token starts the job.
-  3. Automatic previews are held.
-  4. Copies run on the job pool in chunks of 2 or 4 files, each with its size checked and its mtime rounded up to
-     2 s.
-  5. One config commit makes the switch and records the old stores under `cleanup`. The job cannot be cancelled
-     from here.
-  6. The old copies are removed.
-
-  If it fails or is cancelled before the switch, nothing changes. A crash leaves
-  `<data>/data/thumbnail-move.json`, which the next start undoes. Old copies still held open are removed by the
-  next start's "Move thumbnails (finishing)" job. Leaving a folder also removes the previews of this install's
-  sources that are no longer listed (Q320-8).
-- **Remove thumbnails of removed sources** (`scope.mode` `prune`). It is offered in Thumbnail maintenance only in
-  folder mode, and it touches only this install's keys.
-- **Page tests.** `tests/browser/workspace-thumbnail-location.spec.mjs` covers the row, both moves, the in-place
-  refusal, the confirmation, the notice with Recreate and with Use this folder. The legacy gallery runs once in
-  folder mode (`workflows.spec.mjs`). The hooks are `tests/browser/thumbnail_location_fixture.py`.

-    "(3 sources, 8,512 thumbnails)" counts, because counting means walking every preview on each view. It says
-    "Using the default folder next to your library." and names old copies that wait to be removed.
-- D197: the Move thumbnails review uses the shared review.
-  - A grid value may be a lead sentence with a list (`[lead, items]`).
-  - Sources no longer listed appear under "Removed after the move", where the mock has a "Not moved" row
-    (maintainer answer to Q320-8: remove).
-  - The Free space line is "<size> free", without naming the disk.
-- D198: Activity's view of `mode: move` and `mode: prune`.

-- D199: the unavailable notice on Overview and Sources & scans.

-
-Before #546 a Pair node run saved its category and tags on the saved pair
-only; the positive prompt it created stayed Uncategorized and untagged. This
-plan fills the **empty** category and the **empty** tag set of those prompts
-from their saved pairs (``docs/egm/post-3.4.1/550-design.md``):
-
-- Considered: prompts the Pair node created as a positive (their earliest
-  pair, in either role, has them as the positive and its ``created_at`` is
-  within ``PAIR_CREATED_TOLERANCE`` of theirs) whose category is blank
-  and/or that have no tags.
-- Sources: the prompt's non-archived pairs where it is the positive. Pairs
-  with a blank category or no tags are ignored for that field. A field fills
-  when exactly one value remains (category: trimmed, case-sensitive; tags:
-  the tag-id set).
-- Kept (protected), in this order: archived prompt, edited prompt
-  (``updated_at`` not within the tolerance of ``created_at``), pairs that
-  disagree, a tag set over ``MAX_LIBRARY_TAGS``.
-
-The apply runs in the caller's ``BEGIN IMMEDIATE`` transaction, recomputes
-the fingerprint, then writes guarded statements (the field must still be
-empty) that never touch a pair, a negative or ``updated_at``. A guard that
-hits nothing raises ``PlanChanged`` so the whole transaction rolls back.
