[Bug] My Sites dashboard layout doesn't adapt to long site names

[ratul01047]

Problem: Site names that are longer than the fixed container width get truncated or cause layout issues in the My Sites dashboard.

Current Behavior: ​https://www.awesomescreenshot.com/image/55409211?key=e2878c76ab4d9779e9dc7a7ce348457a

Expected Behavior: Site containers should adapt to content width for better readability.

Proposed Solution: Add width: auto or similar responsive styling to site list items.

This calls attention to a few things about the list on the My Sites page:

1. @ratul01047's image shows a single narrow container for a network of one site (using the subdomain as its Site Title). [33072] made columns responsive, but it set width percentages for up to six columns without checking if the user's total is fewer than that.
2. PR 9242 adds CSS to break long words onto multiple lines if necessary. That works, yet reusing the word-wrap-break-word class on the ul (or the individual li elements) would achieve the same goal.
   <ul class="my-sites striped word-wrap-break-word">
3. The My Sites page has h3 headings that skip the h2 level. Both elements are styled the same, so the headings could be changed to h2 rather easily.
4. Further outside the original scope of this ticket, any Global Settings content outputs inside the ul without its own li. This was a table row with two columns before [33072], so the content might not belong inside the list. I did not find any ​examples of the filter using the 'global' context.
