fix: PDF-Export — Dateiname, Fettschrift, Zeichen, Abstaende, Zertifizierungen rechts

5 Korrekturen am Experten-Profil PDF-Export:
1. Dateiname: Vorname_Nachname_CV.pdf/.docx (RFC 5987 Umlaut-sicher)
2. Fettschrift: Zeitraum, Firmenname und Branche in Berufserfahrung
3. Zeichen-Darstellung: Markdown-Marker (**bold**/*italic*/__u__)
   werden aus Tasks-Text entfernt, doppelte Bullet-Praefix-Normalisierung
4. Abstaende: Sprachen 14->11px, Erfahrung 14->11px, Gap 8->4px
5. Zertifizierungen in rechte Spalte verschoben (nach Berufserfahrung)
   statt als Vollbreite-Sektion am Ende

+### Aenderungen 2026-03-13 (17): Experten-Profil PDF-Export — 5 Korrekturen
+
+#### Backend (Core Service)
+- `expert-profile/profile-export.service.ts` — PDF-Export verbessert:
+  - Neue Helper-Methoden `stripMarkdown()` und `normalizeTaskLine()`
+  - Zeitraum fett (Helvetica-Bold, #555555)
+  - Firmenname + Branche fett (Helvetica-Bold, #333333)
+  - Tasks: Markdown-Marker (**bold**, *italic*, __u__) werden vor Ausgabe entfernt
+  - Sprachen/Erfahrung: Abstand 14px → 11px, Sektion-Gap 8px → 4px
+  - Zertifizierungen in rechte Spalte verschoben (nach Berufserfahrung)
+  - Return-Typ: `Promise<{ buffer, firstName, lastName }>` (war: `Promise<Buffer>`)
+- `expert-profile/profile-export.service.ts` — DOCX analog angepasst:
+  - Zeitraum + Firma fett; normalizeTaskLine() fuer Tasks; Zertifizierungen in rightParagraphs
+- `expert-profile/expert-profile.controller.ts`:
+  - PDF: `Vorname_Nachname_CV.pdf`, DOCX: `Vorname_Nachname_CV.docx`
+  - RFC-5987 `filename*=UTF-8''...` fuer Umlaut-Dateinamen
+
+#### TypeScript
+- `npx tsc --noEmit` in packages/core-service: 0 Fehler
+
+#### Deployment-Hinweis (Schritt 17)
+- Rebuild + Restart: nur core-service
+
