Pages and panels showed inconsistent loading states: the Backup center
and several admin pages (System, SSH, admin Overview), the Overview
Migrate/Peers panels, the per-app updater section and the backup engine
details modal rendered a bare 'Loading…' text line (updater-empty /
backup-empty-state) with no spinner, while Services/Config/Tasks used a
boxed card + spinner.
Add one shared loader — window.lpLoadingBox(message) + .lp-loading CSS in
the core/loading subsystem (the boxed card + accent spinner the good tabs
already use) — and route those bare-text loaders through it. The system
metric graph keeps its absolute overlay but gains the same spinner.

backup/ held 15 loose .js plus css/html at the component root. Split into
per-tab sub-systems mirroring the admin/apps layout:
backup/core/{js,css,html}/ schema, base BackupPage, fetch-client,
cron-schedule, backup.css, backup-content.html
backup/dashboard/js/ backup-dashboard
backup/snapshots/js/ backup-snapshots, backup-snapshot-actions
backup/locations/js/ backup-locations, backup-location-fields,
backup-location-modal, backup-ssh-key
backup/migrate/js/ backup-migrate
backup/configuration/js/ backup-configuration, backup-retention-presets,
backup-engine-details
Updated the scripts[] array + loadFragment in index.js, the backup.css href in
index.html, and the handleBackup() fallback paths in spa.js. No behaviour
change — files moved verbatim (prototype-augment clusters), all 17 referenced
paths verified to resolve, node --check clean.
