Fixes https://github.com/go-gitea/gitea/issues/30005. Regression from
https://github.com/go-gitea/gitea/pull/29945.
There was only once instance of `tw-content-center` before that PR, so I
just ran below command and reverted that one instance.
```sh
perl -p -i -e 's#tw-content-center#tw-items-center#g' web_src/js/**/* templates/**/* models/**/* tests/**/*
```

* some of them are incorrect, which would lead to double escaping (eg:
`(print (Escape $.RepoLink)`)
* other of them are not necessary, because `Tr` handles strings&HTML
automatically

Fix some bugs from #25715, fix#25830
1. `$.locale.Tr ... Safe` needs `Escape`, but not `PathEscapeSegments`
2. The attribute should be `role`
3. The `ComposeBranchCompareURL` already does escaping correctly

This PR makes some fixes:
- do not show the prompt for mirror repos and repos with pull request
units disabled
- use `commit_time` instead of `updated_unix`, as `commit_time` is the
real time when the branch was pushed
This PR will display a pull request creation hint on the repository home
page when there are newly created branches with no pull request. Only
the recent 6 hours and 2 updated branches will be displayed.
