v2026.07.13.1

Automatic-backup refinements — restore a stored backup in one click, a totals line, a last-backup-date fix, and a same-second filename fix.

Backups

• new Restore from the list — each stored automatic backup gains a Restore button (POST /api/auto-backups/restore?name=…) that replaces all current data with that backup and reloads. The upload-import pipeline was refactored into a shared applyStagedImport, and the restore path unpacks the stored ZIP into staged files via stagedFilesFromZip, so restore and upload import go through the same atomic commit and category-save (auto_backup.go, backup.go, main.go). The restore button uses the destructive theme colour with a confirm dialog and marks favicons for prefetch on reload (config/config-backup.js, templates/config.html, locales/{en,nl,de,fr}.json).
• new Totals summary — the Automatic Backups section shows a “{count} backups · {size} total” line under the list, hidden when empty (config/config-backup.js, templates/config.html, locales/{en,nl,de,fr}.json).
• fix Back Up Now updates the last-backup date — an on-demand automatic backup now writes nextdash-last-backup and refreshes the Last backup label, matching the manual ZIP download (config/config-backup.js).
• fix Same-second filenames no longer collide — writeAutoBackup now uses uniqueAutoBackupName, appending a -2, -3, … suffix when several backups are written within the same second, so a rapid Back Up Now no longer overwrites a just-written file. The filename regex accepts the optional suffix, and download/delete/restore share a single resolveAutoBackupPath validator (auto_backup.go).

Developer & docs

• fix Tests — added same-second uniqueness and restore round-trip coverage (plus restore name/traversal rejection) in auto_backup_test.go, and dropped the now-unnecessary sleeps from the rotation test.
• fix README, MANUAL, CHANGELOG & Config Help — v2026.07.13.1 notes.
• fix What's new modal — v2026.07.13.1 JSON entry with a Backups section (no doc-update or cache-bust item, by design).
• fix Cache-bust — whats-new-v156 data version (asset_versions.go, whats-new-stub.js) and 2026.07-dashboard-release-v115 dashboard release token.
