feat: add website social link, fix herkunft origin display, GUI backup schedule, and format-based batch numbering

- SiteSettings gains websiteUrl (e.g. online shop link) alongside the
  existing social links, editable in Verwaltung > Automatisierung.
- /herkunft/[lot] now shows the apiary's Standort instead of its internal
  Name (so multiple apiaries at one location read as one origin), adds
  small icons per social link, and surfaces previously-fetched-but-unused
  data (Honigsorte, Abfülldatum, stat cards) to make the page a richer
  customer-facing info page.
- Backup schedule (path/cron/retention) is now also configurable via the
  GUI (Verwaltung > Backup), stored in a new BackupSettings singleton;
  an env var always wins over the GUI value per field, and the scheduler
  reloads its cron job live when GUI settings change.
- New Automatisierung rules let an admin define a format (e.g.
  "WH-{YYYY}-{SEQ:4}") that auto-generates HoneyBatch.batchNumber and
  BottlingBatch.lotNumber on creation, with an atomic per-rule sequence
  counter and a manual reset. Manual entry still works when the rule is
  inactive.
