feat(v2): Atom-Feed-Konfig-Seite + Eigene-Abos-Verwaltung

Backend (Filter sind seit jeher da):
- /api/feed.xml?bundesland=&partei=&limit=
- /api/subscriptions GET/POST/DELETE

UI:
- /v2/feed: Form mit BL/Partei/Limit, generiert Feed-URL live, Buttons Oeffnen/
  URL-Kopieren/In-Feedly. Default-BL aus Header-Selektor uebernommen
- /v2/abos: Liste eigener Abos + Form zum Anlegen/Loeschen, BL-Dropdown,
  Partei-Freitext, Frequenz daily/weekly
- Sidebar 'Daten'-Gruppe um beide Eintraege erweitert (statt Direkt-Link auf
  /api/feed.xml)
- Beide Routen mit Depends(require_auth) — Anonyme bekommen 401-Redirect
