Repo save file fix

[krystian-panek-vmltech]

fixes #221

[Copilot]

Pull request overview

This PR refactors the RepoResource.saveFile() method to simplify file saving logic by always deleting and recreating files, rather than updating them in place. The changes propagate through the codebase to remove now-redundant explicit file deletion calls.

Key changes:

• Simplified saveFileInternal() to always delete existing files before creating new ones
• Removed explicit thumbnail deletion in example script since saveFile() now handles it
• Enabled direct text input in PathPicker component
• Fixed import ordering in Script.java
