Vito fb9134f081 feat(system): Backup & export (System S9) (#339)
* feat(system): back up, restore and export natively

System > Backup & export replaces its hand-off with the concept's section on the
S8 backend: Back up downloads the verified copy and the status line shows only
what GET /backup/status reports (D103); Review restore stages a chosen file and
shows the server's review in the shared review dialog, Cancel discards the stage
and Restore runs the Database restore job, after which the open views reload
(D105); Export JSON plus the components and saved-pairs exports (D103); Import /
inspect opens the shared Import & inspect dialog; the safety-backup policy saves
through the Save row and scheduled backups offer Manual only (D104). Overview's
Backup status row reads the same status.

Refs #326

* test(system): compare Backup & export with the concept

system-backups-concept.spec compares the section, the Restore preview and the
Import & inspect dialog with the concept in both themes at 1600 and 390 wide,
mapping only D103, D104, D105 (and D15/D55 for the shared Import dialog), and
proves a renamed label, a removed row, a lost danger mark and swapped tokens
are noticed. A review's grid values now wrap anywhere (D105), so a long backup
file name keeps the concept's two equal columns at phone width.

Refs #326

* docs(testing): Backup & export contract (D103-D105)

Refs #326

* test(coverage): raise the frontend floors S9 measured

system-backups.mjs gets its measured floor in place of the provisional one;
admin.js, activity-scan.mjs and maintenance-review.mjs branches go up.

Refs #326

* fix(system): keep a refused or handed-back restore review usable

A Restore refused as busy now opens the same review again with Discard /
Restore, and a restore job whose leases did not drain hands its review back
(scope.review_kept) to the page that started it, which reopens it; every
other path that abandons a token after Restore sends its DELETE, so held
reviews can no longer lock restore out. The kept-review line says where the
review is, and a full review store says what to do (I1). applyPlan resolves
with its outcome and its job tracking now has failing-before proof (N5).

Also: the safety-backup toggle says what the policy does (D104, M2); the
restore picker has no type filter so safety backups can be chosen (M3);
"Export all prompts JSON" names what /export holds (N1); small snapshots
show KB (N3); the duplicated holding and save helpers are shared (N4); a
dismissal test covers Cancel, x, Escape, a replacing dialog and leaving (M1).
