2. Rename `<gitea-origin-url>` to `<origin-url>` and make filenames
match.

TODO:
- [x] Check if removal of `requestAnimationFrame` is possible to avoid
flash of content. Likely needs a `MutationObserver`.
- [x] Hide tippy when button is removed from DOM.
- [x] ~~Implement right-aligned items
(https://github.com/go-gitea/gitea/pull/28976)~~. Not going to do it.
- [x] Clean up CSS so base element has no background and add background
via tailwind instead.
- [x] Use it for org and user page.

It also fixes a secondary issue that we were showing timestamp tooltips
over date, which makes no sense, so these are now gone as well:

(cherry picked from commit 857243bed7f9dccdc597c2941df41e821781cb0f)
There was a question about "how to improve the datetime display for
SSH/PGP/WebAuthn"
https://github.com/go-gitea/gitea/pull/28262#issuecomment-1831141611
The root problem is that `DateTime` misses the "data-tooltip-content"
attribute, which should be used to make the tooltip popup smoothly.
Now the UI is consistent and the end users could see the detailed
hour/minute/second easily by hovering the element.


- Resolves https://github.com/go-gitea/gitea/issues/22493
- Related to https://github.com/go-gitea/gitea/issues/4520
Some admins prefer all timestamps to display the full date instead of
relative time. They can do that now by setting
```ini
[ui]
PREFERRED_TIMESTAMP_TENSE = absolute
```
This setting is set to `mixed` by default, allowing dates to render as
"5 hours ago". Here are some screenshots of the UI with this setting set
to `absolute`:
