Hide "Create a Bucket" in Kanban View

First, thank you for your ongoing work on Vikunja! I know real-time features have been on the roadmap for a while, but I wanted to suggest a potential interim solution that might help with customization.

Would it be possible to implement support for a custom.css file that users could mount in their Docker containers? For example:

  • Designate a path like /app/vikunja/custom/ for user-mounted assets
  • Have the frontend automatically include custom.css if present

This would:

  1. Allow immediate UI customization without core changes
  2. Solve multiple theming requests at once
  3. Maintain clean upgrade paths (since customizations live outside the container)

I believe many users (including myself) would find this helpful while waiting for real-time functionality. What do you think about this approach?
