After:

The username shows as "oauth2" because of
f9fdac9809/services/migrations/dump.go (L99)
I have checked that all usage of `MirrorRemoteAddress` has been updated.

However, it needs to be checked again when backporting.

Part of #27065
This PR touches functions used in templates. As templates are not static
typed, errors are harder to find, but I hope I catch it all. I think
some tests from other persons do not hurt.
There are 2 kinds of ".Editorconfig" in code, one is `JSON string` for
the web edtior, another is `*editorconfig.Editorconfig` for the file
rendering (used by `TabSizeClass`)
This PR distinguish them with different names.
And by the way, change the default tab size from 8 to 4, I think few
people would like to use 8-size tabs nowadays.
