feat: Add sourceUrl support for uploads

[Nicolasara]

Description

Adds support for sending the current page URL as sourceUrl when uploading files or screenshots via the extension.

Changes

• background.js:
  • Updated uploadFile and uploadScreenshot to include sourceUrl in the FormData.
  • Updated context menu and message listeners to pass the current page URL.

Closes chibisafe/chibisafe#756

I made the decision to use the page url as the sourceUrl instead of the direct link to the file itself. Since ChibiSafe provides a new hosting link for the file, tracking the originating context seems better than just storing a duplicate technical URL. Alternatively, we could omit sourceUrl for these types of uploads and keep it exclusive to screenshots.

Open to any of the three options though.

Hi @Pitu, sending a PR for the client side change needed to populate data for the new source url added in chibisafe/chibisafe#758.

Also wanted to say thanks for your work on Chibisafe, it's an awesome open source project.

Hey @Nicolasara thanks for the PR. I have a new extension working that I was planning on releasing this week with a much improved UI, and that one already supports sourceUrl. So I'm gonna close this PR and release the new extension in the next few hours.

That being said, the extension wont be uploaded to the stores for a few days, I want a few people to try it before I push it.

Nice! Happy to try it out once it's released.
