improve partial: correct use of tags + attachment links styling

[patriciomacadden]

The partial used <p> elements for each attribute, which auto-close if it contains a <div> element (see the technical summary of the p tag). To avoid this, I'm changing the p elements to div elements.

Also, adding some basic styling for the attachment links.

See before and after screenshots:

before	after	comment
		the space between "Documents" and the links changed due to the correct use of tags, and the links now are styled differently (similar to "forgot your password?" link
		the p element auto-closed due to the inner div, by changing it to a div we produce a better output

Because tailwind v4 just shipped, I'm going to hold off until this gem properly supports it, then we can make sure this PR is styled appropriately for v4.
