[MERGE] tools, base, *: improve image tools

Merge commit for PR: #31811

The main goal is to keep the image ratio on resize (instead of adding a white border).

The opportunity is taken to also clean up the image tools.

See individual commit messages for more information.

Functional:

- Remove the white border from all images (never resize to square, keep aspect ratio)
- Prevent some images from being 3px shorter than expected
- Resize the website favicons appropriately, always encode them as ICO, add a default favicon to new websites
- Secure images going through the tools by returning an error when non-image content is given
- Incrase the max image filesize from 42e6 to 45e6 to fit some of the biggest images we might get from Unsplash
- Always return the correct mimetype/Content-Type for images
- The avatar placeholder was white displayed on top of white, now it's grey so we can actually see it

Technical:

- make image tools more consistent by merging the tools and removing duplicate code
- add tests for the image tools
- remove uncessary parameters
- remove the "ghost border fix"
