feat: connect CMS content, add ISR, Lexical renderer, and hero styling

- Fix tenant ID (1→4) to match CMS content
- Change homepage slug from "home" to "startseite"
- Add ISR with 60s revalidation for automatic content updates
- Create Lexical JSON→HTML renderer for rich text blocks
- Wire up dynamic favicon from CMS site-settings

-# SSL-Monitor Phase 1: Foundation
-
-## Kontext
-- Verzeichnis: /home/frontend/ssl-monitor
-- Tech Stack: Next.js 15 (App Router), Tailwind CSS, shadcn/ui, SQLite (better-sqlite3), BullMQ
-- Port: 3009
-- Redis: localhost:6379 (existiert bereits)
-
-## Ziel
-Grundgerüst mit funktionierendem SSL-Check und Dashboard erstellen.
-
-## Aufgaben
-
-### 1. Projekt-Setup
-- [ ] Next.js 15 mit App Router initialisieren (falls nicht vorhanden)
-- [ ] Dependencies installieren: better-sqlite3, bullmq, ioredis, zod, date-fns
-- [ ] Tailwind CSS + shadcn/ui konfigurieren
-- [ ] Projektstruktur gemäß umsetzung.md anlegen
-
-### 2. Datenbank
-- [ ] SQLite Schema erstellen (src/lib/db.ts)
-- [ ] Tabellen: domains, ssl_checks, categories, settings
-- [ ] Initial-Seed: 3 Default-Kategorien (Development, Production, External)
-- [ ] Initial-Seed: 16 Domains aus umsetzung.md
-
-### 3. SSL-Checker
-- [ ] src/lib/ssl-checker.ts: tls.connect() Implementation
-- [ ] Zertifikat-Parsing (Issuer, Subject, Validity, SANs)
-- [ ] Certificate Chain Analyse
-- [ ] OCSP-Status Check (src/lib/ocsp-checker.ts)
-- [ ] Error-Handling mit Kategorisierung (dns, connection, certificate, timeout)
-- [ ] Retry-Logik (Exponential Backoff)
-
-### 4. Queue System
-- [ ] src/lib/queue.ts: BullMQ Queue Setup
-- [ ] worker/ssl-worker.ts: Worker Process
-- [ ] Concurrency: 5 parallele Checks
-- [ ] Job-Options: 3 Attempts, Exponential Backoff
-
-### 5. API Routes
-- [ ] GET/POST /api/domains - Domain CRUD
-- [ ] GET/PUT/DELETE /api/domains/[id]
-- [ ] POST /api/check - Single Domain Check (queued)
-- [ ] POST /api/check/all - Alle Domains checken
-- [ ] GET /api/history/[domainId] - Check History
-
-### 6. Dashboard UI
-- [ ] src/app/page.tsx: Dashboard mit Grid Layout
-- [ ] components/dashboard/DomainCard.tsx: Expandable Card
-- [ ] components/common/StatusBadge.tsx: Ampel (Grün/Gelb/Rot/Grau)
-- [ ] components/dashboard/FilterBar.tsx: Kategorie + Status Filter + Suche
-- [ ] components/domain/CertificateChain.tsx: Chain Visualisierung
-
-## Erfolgskriterien
-- [ ] `pnpm build` erfolgreich
-- [ ] `pnpm lint` ohne Errors
-- [ ] Dashboard zeigt alle 16 Domains
-- [ ] SSL-Check für eine Domain funktioniert (manueller Test)
-- [ ] Queue-Worker startet und verarbeitet Jobs
-- [ ] StatusBadge zeigt korrekte Farben basierend auf daysRemaining
-
-## Selbst-Prüfung nach jeder Iteration
-1. `pnpm lint --fix`
-2. `pnpm build`
-3. Falls Fehler: analysieren, korrigieren, wiederholen
-4. Falls Build erfolgreich: nächste Aufgabe
-
-## Bei Blockade nach 40 Iterationen
-- Dokumentiere in BLOCKERS.md was nicht funktioniert
-- Liste versuchte Ansätze
-- Markiere welche Aufgaben abgeschlossen sind
-
-## Referenz
-Lies /home/frontend/ssl-monitor/umsetzung.md für Details zu:
-- Datenbank-Schema (Abschnitt 2.2)
-- SSLCheckResult Interface (Abschnitt 3.2.1)
-- Domain-Seed Daten (Abschnitt 5.3)
-
-Output <promise>PHASE1_COMPLETE</promise> wenn alle Aufgaben erledigt.
