fix: resolve 3 i18n errors and fix shared package exports ordering

- Skill Matrix: use correct nested key `skillMatrix.title` instead of
  `skillMatrix` which resolved to the full object
- Skill Matrix: use `skillMatrix.trend.label` instead of
  `skillMatrix.trend` which resolved to the trend object
- Integrations: rename duplicate `title` key to `documentTitle` in
  de.json/en.json to prevent the ecoDMS column header from overriding
  the page title ("Titel" instead of "Integrationen")
- Shared package: move `types` condition before `import`/`require` in
  exports field to fix TypeScript type resolution
