fix: allow anonymous theme switching when REQUIRE_SIGNIN_VIEW is set (#38956) (#38961)

Backport #38956 by @bircni

Fixes https://github.com/go-gitea/gitea/issues/38950

`POST /-/web-theme/apply` used the `optSignIn` middleware, which forces
sign-in when `REQUIRE_SIGNIN_VIEW` is enabled. This made theme switching
unusable for anonymous users (e.g. on the sign-in page), even though the
handler already supports anonymous users by storing the choice in a
cookie.

This was an unintended regression from
https://github.com/go-gitea/gitea/pull/36183, which replaced the route's
CSRF-only middleware with `optSignIn`, incidentally pulling in the
sign-in requirement meant for content routes.

The fix drops the sign-in requirement for this route while keeping
cross-origin protection and the usual signed-in-user checks
(inactive/prohibited login, forced password change).
