refactor(settings): remove the redundant Erinnerungen hub page

The standalone /settings/reminders page was a link-only hub that merely
deep-linked into the canonical editors — duplicating the Notifications
entry. Drop the section, its slug, and its placeholder/route wiring, and
301-redirect /settings/reminders to /settings/notifications. Reminder
types consolidate onto the Notifications home in a follow-up.

- * screen, and the new Vorsorge (preventive-care) reminders had their own

- *
- *   - CHANNELS — the *how/where* a reminder is delivered (APNs / Telegram /
- *     ntfy / Web Push / Webhook / Email). These keep living on the
- *     Notifications channel screen; this hub links to them.
- *   - CATEGORIES — the *what/when*: medication, mood, Vorsorge, low-stock
- *     runway, and the proactive Coach nudge. Each keeps its own canonical
- *     editor and deep link; the hub just gathers them so the concept reads
- *     as one place.
- *
- * Consolidation by linking — every existing editor stays intact and
- * deep-linkable; nothing here is a rewrite.
