Fix: add missing repository field to package.json files for npm provenance

[vraja-pro]

Context

When publishing npm packages with --provenance, npm registry verifies that the repository.url in package.json matches the GitHub repository URL recorded in the provenance statement. Several packages were missing the repository field entirely (treated as ""), causing a 422 error from the npm registry during publishing.

Summary

This PR can be summarized in the following changelog entry:

• Adds missing repository field to package.json for packages that lacked it, fixing npm provenance verification during publishing.

Relevant technical choices:

• Added the repository field with type, url, and directory to the seven package.json files that were missing it: tailwindcss-preset, ui-library, related-keyphrase-suggestions, dashboard-frontend, e2e-tests, jest-preset, and postcss-preset.
