feat(17-03): "Meine Quellen" wird vollstaendig — Postfach, eigene Feeds, Benachrichtigung

- RssFeedSource bekommt isPlatformWide (server-derived), createRssFeed nimmt
  einen scope-Parameter (personal/platform, Vorgabe personal)
- RssFeedListForm bekommt scope-Prop: personal zeigt eigene Feeds editierbar +
  plattformweite als schlichte Aufzaehlung ohne Knoepfe darunter; platform
  zeigt nur plattformweite Feeds editierbar
- DigestIntervalForm aus settings/page.tsx unveraendert herausgeloest (keine
  neuen Beschriftungen, gleiche settings.*-Schluessel)
- my-sources/page.tsx um "Meine Feeds" und "Benachrichtigung" erweitert,
  Verweis auf die Administrationsseite nur fuer ADMIN/SUPER_ADMIN
- settings/page.tsx vorgezogen auf RssFeedListForm scope="platform" (Rule 3,
  eigener Type-Check-Verify sonst rot) — volle Rollenpruesung folgt Task 2

Rule 1: createRssFeed's Antwort traegt kein isPlatformWide (nur GET mappt es
serverseitig) — RssFeedListForm setzt es nach dem Anlegen lokal aus dem
verwendeten scope, sonst wuerde ein frisch angelegter plattformweiter Feed
bis zum naechsten Neuladen aus seiner eigenen Liste verschwinden.

+ * 17, D-01/D-02/D-04/D-05).
  *
- * Until this plan, the alert mailbox lived on the admin-only
- * `/modules/tender-radar/settings` page, one config per TENANT — a second
- * colleague with their own portal account could not connect their own
- * inbox. Phase 17 moves ownership to the USER (TenderEmailConfig.userId).
- * This page is where every user with module access manages their own
- * mailbox, reusing the existing `EmailAlertConfigForm` UNCHANGED — it
- * already talks to the same `GET`/`PUT /modules/tender-radar/email-config`
- * endpoints, which now resolve ownership by userId instead of tenantId
- * (TendersController.getEmailConfig/saveEmailConfig).
- *
- * Deliberately a SEPARATE page from `/settings` (D-01 open point 4), not a
- * new section on `/settings/general`: module-specific settings stay with
- * the module rather than accumulating on a generic account page as more
- * modules adopt the same per-user pattern (DKV-Fleet, future modules).
+ * Plan 01 built this page with a single section (the mailbox). Plan 03
+ * (D-04, the original backlog trigger) completes it with two more: the
+ * caller's own RSS feeds (`RssFeedListForm scope="personal"` — reused
+ * unchanged from the admin settings page, Plan 02's `isPlatformWide` split
+ * decides what's editable here) and the digest interval
+ * (`DigestIntervalForm`, extracted from the settings page — it was already
+ * per-user, D-01/D-03 of Phase 12, only misplaced). Together: mailbox, own
+ * feeds, own notification cadence — everything a normal module user is
+ * allowed to touch, on one page, in one scroll.
  *
  * D-05 (harte Grenze): `Tender` stays platform-global — connecting a
- * mailbox here only changes WHO feeds sources in, not WHO sees hits. The
- * intro text below says so explicitly, so nobody is surprised that a
- * colleague's inbox produces results everyone at the tenant can see.

+ *
+ * Administrators additionally see a link to the admin-only settings page
+ * (poll interval, platform-wide feeds) — everyone else does not, because
+ * that page rejects them anyway (Plan 03, D-03). The role comes from the
