Fix end-user-facing uses of inline CSS (#13438)

* Move some inline styles to CSS files

* Move default_account_display_name span to fix useless tags with duplicate id

* Change handling of public pages spoiler text from inline CSS to dataset attribute

* Use the `dir` HTML attribute instead of inline CSS

* Move status action bar inline CSS to CSS file

* Hide logo resources from CSS file, not inline CSS

Fixes #11601

* Move translation prompt styling from inline CSS to CSS file

* Move “invited by” styling on registration form from inline to CSS file

* Use the progress tag to display poll results in JS fallback

* Fix poll results JS-less fallback when the user has voted for an option

* Change account public page “moved” notice to use img tags instead of inline CSS

* Move OTP hint inline CSS to SCSS file

* Hide JS-less fallback vote progressbars from accessibility tools
