A brief introduction to Same-Site cookies (and the difference between strict and
lax) can be found at
https://blog.mozilla.org/security/2018/04/24/same-site-cookies-in-firefox-60/

TLDR: We use lax since we want the cookies to be sent when the user navigates
safely from an external site.

If an unresolved report for the same target account already exists,
no new notification is generated

Add tests to avoid similar issues in the future

* Add missing specs for relay accept/reject

* Display pending message on admin relays UI

Fixes #8463

Add forgotten custom CSS admin setting strings

* Instead of rejecting login, show forbidden error when login disabled

Avoid confusion because when login is rejected, the message is that
the account is not activated, which is wrong.

* Fix tests

* Add default_settings class method to ScopedSettings

ScopedSettings was extended to use value of unscoped setting instead of
only using defaults set in config/settings.yml for selected settings.
This adds possibility for admins to set default values of users' settings,
for example default theme (as requested in #7092).

* Add ability to change an instance default theme

Initially I thought there might be valid reasons for remote users to
have a different, unpredicted username format. However, I now realize
such a difference would be unusable and unexpected within Mastodon.
