This commit:

- Refactors centered text blocks currently used for placeholders
  for empty tables and puts styles for it in separate class -
  .centered-text, simply aliasing text-align: center. Which is
  furtherly used in this commit.

- Improves applications settings page to use heading actions, moving
  "New application" button there, and displaying placeholder "You
  have no applications" in place of empty table.

- Improves custom emoji settings page to use heading action
  for "Upload" button, making it more easily accessible without
  need to scroll through all of the emojis.

- Improves email domain blocks settings page, moving "Add new" to the
  heading actions and using placeholder "No e-mail domains currently
  blacklisted" instead of showing empty table.

When you have many filters, it may be hard for you to reach the button
to create yet another one. This commit moves creation button to the
heading, leaving the page just for the list.

On the other hand, when there are no filters, page looks kind of
strange with the empty table. So text stating obvious fact that user
has no filters was added in this commit too.

Closes #11020
Closes #12790

This commit adds promotional notice on appearance settings about
translation project if any other locale than English is used. It
allows users to learn and contribute translations to Mastodon.

Step ahead, in this commit one unusual string is added - link to a
guide. By default it refers to Crowdin project itself, but if any of
Mastodon localization teams established their own guide, they can
refer it. Or, if Crowdin supports localized domain for language, it
can also be put there (e.g. https://fr.crowdin.com/...).

Currently the page re-uses strings from other contexts which doesn't fit
very well - strings incorrectly lowercase-d and pluralized, when they
don't need to be, because it's a table.

This commit changes page to re-use accounts.posts_tab_heading for toots,
and admin.accounts for "Following" and "Follows". This all should look
more aesthetically pleasing.

* Remove unused “salmon_url” string

* Remove more unused translatable strings

The following strings all used to be on the admin account page
but aren't used anymore: profile_url, outbox_url, followers_url, feed_url

Pluralize function from Rails framework does not work with other
languages than English, moreover it does not even work properly with
English [1]. Not that the latest applies to this context, it's just
a sign that we best to avoid this function, especially when there are
more reliable ways.

This commit changes how reports pages generated in order to avoid usage
of pluralize function, replacing it with default translation function,
called with given counter. On top of that, we have to make strings
pluralizable, so have to change locale files.

* Show badge on group actor in WebUI

* Do not notify in case of  by following group actor

* If you mention group actor, also mention group actor followers

* Relax characters that can be used in username (same as Application)

* Revert "Relax characters that can be used in username (same as Application)"

This reverts commit 7e10a137b8.

* Delete display_name method

Before this moment relationships managing page was using strings from
other context - from counters, but in order for translators to be able
to translate it relatively to the page, it must use separate strings.

I've split the strings for "Following" and "Followers" and put them to
"relationships" keyset in localization file. This should solve this
issue.

Fixes #10863

* Add ability to filter reports by target account domain
