Add TUI publish feature and fix web UI dropdown

- Add Publish button to TUI for publishing tools directly from the
  graphical interface without using the command line
- Fix user dropdown menu in web UI header that stayed open after
  clicking (replaced Alpine.js directives with vanilla JS)
- Update test to use correct registry URL (cmdforge.brrd.tech)
