fix: upgrade to Next.js 16.2.1 and resolve bundling issues

- Fixed client bundle contamination by moving child_process-dependent code
- Created standalone /api/robots/command route for SSH robot commands
- Created plugins router to replace robots.plugins for plugin management
- Added getStudyPlugins procedure to studies router
- Fixed trial.studyId references to trial.experiment.studyId
- Updated WizardInterface to use REST API for robot commands
