Reduce number of hover tooltips for informative content

Steps to reproduce

This is an accessibility issue.

Tooltips can be a good way of giving extra information or clarifying something, but if it’s important it’s usually better to always show it.
Information icons and times, for example, when a document last was changed, have got tooltips.
But since these aren’t interactive objects they’re not reachable with the keyboard.

Expected behavior

If the information in a tooltip is important for the user to understand the contents, consider just placing it directly on the page instead of hiding it in a tooltip.

It might be best to just write out the full text in these instances. For example “6 days ago. 23 March at 16:29.”

Solution could be to improve tooltips, which is a separate ticket https://github.com/nextcloud/nextcloud-vue/issues/2503.

Also could be a suggestion to use a full text instead of using tooltips.

Additional info

No files or tests are named. Start by locating the mail UI components that render informative tooltips for information icons and relative timestamps, then compare them with the screenshot and the accessibility concern described. Done means important information is visible on the page without requiring hover or keyboard-inaccessible controls.
