Author distrobox.ini files from a GUI form (Roadmap: Needs External Help)

[kacperpaczos]

• I have read the FAQs (https://dvlv.github.io/BoxBuddyRS/faqs)
• My feature is not on the Roadmap (https://dvlv.github.io/BoxBuddyRS/ROADMAP)
• I have searched for previous issues (https://github.com/Dvlv/BoxBuddyRS/issues?q=is%3Aissue+is%3Aclosed)

Describe your feature request below

Another one off the Needs External Help list: "Create Assemble ini files via GUI". BoxBuddy can already assemble a box from an .ini, but you have to hand-write the file first, and I never remember the exact keys. A small form that writes the file for me would close that loop.

This is what I put together — a form for the section name, image, packages, home and the init/nvidia switches, with a live preview of the exact file contents underneath so there's no guessing what gets written:

Save drops it wherever you pick, defaulting to <section>.ini in Documents, and it's ready to feed straight back into the existing Assemble action.

I have it working and can open a PR.
