maziggy 9ba1e34729 fix(archives): keep Quick Stats contribution when deleting a print (#1343)
Reported by @IndividualGhost1905: printing the same model ten times and
  then deleting nine archive entries (to keep the file list tidy) silently
  rewound the totals on the Statistics page — total prints, filament,
  cost, and per-print energy all dropped back to whatever the surviving
  row contributed, as if the other nine prints had never happened.

  Root cause: every metric in get_archive_stats is recomputed live from
  PrintArchive rows via COUNT / SUM, so removing a row removes its
  contribution. Energy in the default "Total" mode already survived
  deletion because it reads the smart-plug lifetime counters — that's
  the architectural shape we now generalise to the rest.

  Fix: soft delete with opt-in hard purge.

  Backend:
  - New nullable, indexed deleted_at column on print_archives, dialect-
    conditional migration (DATETIME on SQLite, TIMESTAMP on PostgreSQL).
  - ArchiveService.soft_delete_archive flips deleted_at and removes the
    files from disk (still reclaims storage); the path-safety checks were
    extracted into _resolve_archive_dir_for_delete so soft and hard delete
    share the rules.
  - DELETE /archives/{id} accepts ?purge_stats=true; default is soft.
  - Listings filter deleted_at IS NULL: list_archives, search FTS + LIKE
    fallback, GET /{id} (404 on soft-deleted), tag listing, duplicate
    detection (so a 1-live + 9-soft-deleted group no longer marks the
    survivor as a duplicate), and ArchiveComparisonService's "similar"
    suggestions. GET /stats and GET /slim deliberately do NOT filter so
    Quick Stats and the dashboard widgets keep counting deleted prints.

  Frontend:
  - ConfirmModal gained an optional children slot.
  - ArchivesPage (both card and detail views) own a per-instance
    deletePurgeStats boolean and render an opt-in checkbox in the delete
    dialog; resets to off on every close so the destructive option is
    never sticky.
  - api.deleteArchive(id, purgeStats?) appends ?purge_stats=true only
    when the box is ticked.
  - One new i18n key archives.modal.deletePurgeStats added across all 8
    locales (full German, English fallbacks elsewhere).
