fix(archives): bulk and auto purge now honour the soft / hard delete choice from #1343 (#1390 follow-up)

  Reporter IndividualGhost1905 followed up after the #1378 / #1343
  backfill landed and pointed at the next inconsistency: the per-
  archive delete dialog has had a "Also remove this print from Quick
  Stats" checkbox since #1343, but the "Purge Old" button and the
  scheduled daily auto-purge sweeper both ignored that choice and
  hard-deleted unconditionally. From the user side this looked like
  "automatically deleted from statistics without any warning" — half-
  true, and the inconsistency was real either way.

  The actual current shape (before this fix):

    - POST /archives/purge -> archive_purge_service.purge_older_than
      -> ArchiveService.delete_archive (hard). Archive row dropped.
      Linked PrintLogEntry rows have ON DELETE SET NULL so they
      survive as orphans with archive_id=NULL. Quick Stats keeps the
      filament / cost / energy contribution because the log rows are
      still there, but the archive-list-iterating widgets (Filament
      Trends, By Material, Color Distribution, Printer Stats) lose
      the row, and Time Accuracy loses its join target. Visibly
      inconsistent.
    - Scheduled _maybe_run_auto_purge -> same code path, same effect.
    - Single-archive DELETE /archives/{id} -> already takes
      purge_stats=true|false (default false=soft) and routes either
      soft_delete_archive (keeps everything, flips deleted_at) or
      deletes PrintLogEntry rows first + hard-deletes archive.

  The fix threads the same purge_stats flag through every bulk surface
  with soft as the default, matching the single-archive default:

  Backend:
    - archive_purge_service.purge_older_than(..., purge_stats=False)
      -> per-row soft_delete_archive when False, per-row
      PrintLogEntry deletion + delete_archive when True. Each runs in
      its own session (same pattern the sweeper already used).
    - preview_purge gains the same kwarg so the eligible-count
      matches what an actual run would touch: soft mode excludes
      already-soft-deleted rows, hard mode counts them as eligible
      for promotion.
    - get_settings / set_settings now persist archive_auto_purge_stats
      (default False). _maybe_run_auto_purge reads it on every tick.
    - ArchivePurgeRequest / ArchivePurgeResponse / ArchivePurgeSettings
      schemas extended.
    - Route /archives/purge accepts the body flag, /purge/preview
      accepts the query param, /purge/settings GET + PUT echo the
      setting.

  Frontend:
    - "Purge old archives" modal: new "Also remove from statistics"
      checkbox under the preview, unchecked by default. Plumbed into
      the preview query key + the execute mutation.
    - Settings -> Archives auto-purge card: matching toggle next to
      the days slider, disabled when auto-purge itself is off.
    - api.previewArchivePurge / api.executeArchivePurge accept the
      flag; ArchivePurgeSettings type gains purge_stats.
    - All 8 locales (en, de, fr, it, ja, pt-BR, zh-CN, zh-TW) get
      new purgeStatsLabel / purgeStatsHint / purgeStatsDescription
      keys, plus rewritten effect / warning copy in archivePurge and
      archiveAutoPurge to reflect that the default no longer
      "permanently removes from the database" but instead hides the
      row + removes files while keeping Quick Stats intact. i18n
      parity check clean: 4814 keys across all 8 locales, no fallback.

  Behaviour change for existing users on auto-purge: the sweeper used
  to hard-delete by default and now soft-deletes by default. After
  the upgrade those installs start *preserving* more data in Quick
  Stats rather than losing it — safer direction of the two, but worth
  the explicit call-out. Anyone who wants the old behaviour ticks the
  new toggle once and it persists.
