Remove hard-coded German locale and improve English localization

- Change default locale from German to English in VSMain.java
- Fix language key typos: "loging" → "logging" throughout codebase
- Improve English language strings:
  - "Insert" → "Add" for better UX terminology
  - "Fullfilled" → "Fulfilled" (spelling correction)
  - "GLobal" → "Global" (capitalization fix)
  - "Delete logs" → "Clear logs" (more appropriate action)
- Update all references to changed language keys
