chore: migrate to mobiletic-labs org and rename npm scope

- Git URLs: git.mobiletic.net/mobiletic/anonymizer -> .../mobiletic-labs/anonymizer
  (homepage, repository, bugs, CI badge, clone instructions).
- npm package renamed @mobiletic/anonymizer -> @mobiletic-labs/anonymizer
  across package.json, lockfile, README, CONTRIBUTING, examples, issue template.
