[#1349] Basic Cookie Authentication (#1498)

* [#1349] Stub basic cookie authentication

* [#1349] Basic login page

Also adjusts WebView header color and shadow to match WebUI. WebUI uses
a background-image gradient to change the perceived color, which was not
noticed originally.

* [#1349] Handle login post

* [#1349] Redirect to previous URL

* [#1349] Return a basic 401 for api endpoints

Instead of redirecting to a visual login page, API should just indicate
the bad state

* Use more appropriate 303 redirect

* Update server/src/main/kotlin/suwayomi/tachidesk/server/JavalinSetup.kt
