Add user status filter to admin user management page (#16770)

It makes Admin's life easier to filter users by various status.

* introduce window.config.PageData to pass template data to javascript module and small refactor

move legacy window.ActivityTopAuthors to window.config.PageData.ActivityTopAuthors
make HTML structure more IDE-friendly in footer.tmpl and head.tmpl
remove incorrect <style class="list-search-style"></style> in head.tmpl
use log.Error instead of log.Critical in admin user search

* use LEFT JOIN instead of SubQuery when admin filters users by 2fa. revert non-en locale.

* use OptionalBool instead of status map

* refactor SearchUserOptions.toConds to SearchUserOptions.toSearchQueryBase

* add unit test for user search

* only allow admin to use filters to search users
