feat(frontend): bullet-editor fuer Projektaufgaben + Popup-Backdrop deaktiviert

- Modal.tsx + Drawer.tsx: onClick={onClose} vom Backdrop entfernt — alle
  Popups schliessen sich jetzt nur noch ueber Speichern/Abbrechen-Buttons
- ProjectModal.tsx: Textarea "Aufgaben" durch BulletEditor-Komponente
  ersetzt (Toolbar-Button toggled Aufzaehlungspunkt, Enter setzt Bullet
  auf naechster Zeile fort, leere Bullet-Zeile + Enter beendet die Liste)
- ExpertProfileTab.module.css: CSS fuer bulletEditor, bulletToolbar,
  bulletBtn, bulletEditorTextarea hinzugefuegt

+### Aenderungen 2026-03-13 (13): Experten-Profil – Bullet-Editor fuer Aufgaben + Popup-Backdrop deaktiviert
+
+#### Frontend
+- `components/Modal.tsx` — `onClick={onClose}` vom Overlay-div entfernt: Popups schliessen sich nicht mehr durch Klick neben das Popup (betrifft alle Modal-Instanzen im Projekt)
+- `components/Drawer.tsx` — Gleiches: Drawer schliesst sich nicht mehr durch Klick auf den Backdrop
+- `profile/sections/ProjectModal.tsx` — Neue lokale `BulletEditor`-Komponente (keine externe Library): Toolbar mit "☰ Liste"-Button (toggled `• ` am Zeilenanfang ein/aus), automatische Aufzaehlungsfortsetzung beim Enter-Druck, leere Bullet-Zeile `• ` + Enter beendet die Liste; ersetzte die einfache `<textarea>` im Feld "Aufgaben"
+- `profile/ExpertProfileTab.module.css` — Neue CSS-Klassen: `.bulletEditor`, `.bulletToolbar`, `.bulletBtn`, `.bulletEditorTextarea`, `.bulletBtn:hover`; Editor-Container mit `border + :focus-within`-Ring analog zu Input-Feldern; Textarea innerhalb des Editors hat keinen eigenen Rand (verhindert doppelten Rahmen)
+
+#### TypeScript
+- `npx tsc --noEmit` in packages/frontend: 0 Fehler
+
+#### Deployment-Hinweis (Schritt 13)
+- Rebuild + Restart: nur frontend (kein Backend-Aenderung)
+
+---
+
+### Aenderungen 2026-03-13 (12): Bug-Fix Sprachen im Experten-Profil
+
+#### Backend (core-service)
+- `core/expert-profile/dto/create-language.dto.ts` — `@IsIn` Validator um fehlende Werte erweitert: `Verhandlungssicher`, `Fliesend`, `Gut` waren nicht enthalten (Frontend sendete diese Werte → 400 Fehler); alle 10 Werte jetzt korrekt: `['Muttersprache', 'Verhandlungssicher', 'Fliesend', 'Gut', 'C2', 'C1', 'B2', 'B1', 'A2', 'A1']`
+
+#### Deployment-Hinweis (Schritt 12)
+- Rebuild + Restart: nur core-service
+
+---
+
 ### Aenderungen 2026-03-13 (11): Kontakt-Detailseite – Breite, Outlook-Daten-Sektion, Felder, Outlook-Push
 
 #### Backend (crm-service)
