OIDC: case-insensitive comparison for auth scheme Basic (#31706)
@kylef pointed out on https://github.com/go-gitea/gitea/pull/31632 that
[RFC7617](https://www.rfc-editor.org/rfc/rfc7617.html#section-2)
mandates case-insensitive comparison of the scheme field `Basic`. #31632
copied a case-sensitive comparison from
https://github.com/go-gitea/gitea/pull/6293. This PR fixes both
comparisons.

The issue only affects OIDC, since the implementation for normal Gitea
endpoints is already correct:

fix OIDC introspection authentication (#31632)
See discussion on #31561 for some background.

The introspect endpoint was using the OIDC token itself for
authentication. This fixes it to use basic authentication with the
client ID and secret instead:

* Applications with a valid client ID and secret should be able to
  successfully introspect an invalid token, receiving a 200 response
  with JSON data that indicates the token is invalid
* Requests with an invalid client ID and secret should not be able
  to introspect, even if the token itself is valid

Unlike #31561 (which just future-proofed the current behavior against
future changes to `DISABLE_QUERY_AUTH_TOKEN`), this is a potential
compatibility break (some introspection requests without valid client
IDs that would previously succeed will now fail). Affected deployments
must begin sending a valid HTTP basic authentication header with their
introspection requests, with the username set to a valid client ID and
the password set to the corresponding client secret.

allow synchronizing user status from OAuth2 login providers (#31572)
This leverages the existing `sync_external_users` cron job to
synchronize the `IsActive` flag on users who use an OAuth2 provider set
to synchronize. This synchronization is done by checking for expired
access tokens, and using the stored refresh token to request a new
access token. If the response back from the OAuth2 provider is the
`invalid_grant` error code, the user is marked as inactive. However, the
user is able to reactivate their account by logging in the web browser
through their OAuth2 flow.

Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.

### Notes on updating permissions
Ideally, we would also refresh permissions from the configured OAuth
provider (e.g., admin, restricted and group mappings) to match the
implementation of LDAP. However, the OAuth library used for this `goth`,
doesn't seem to support issuing a session via refresh tokens. The
interface provides a [`RefreshToken`
method](https://github.com/markbates/goth/blob/master/provider.go#L20),
but the returned `oauth.Token` doesn't implement the `goth.Session` we
would need to call `FetchUser`. Due to specific implementations, we
would need to build a compatibility function for every provider, since
they cast to concrete types (e.g.
[Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132))

Note for testing. You need to run gitea using `https` to get the full
passkeys experience.

Return access_denied error when an OAuth2 request is denied (#30974)
According to [RFC
6749](https://datatracker.ietf.org/doc/html/rfc6749#section-4.1.2.1),
when the resource owner or authorization server denied an request, an
`access_denied` error should be returned. But currently in this case
Gitea does not return any error.

For example, if the user clicks "Cancel" here, an `access_denied` error
should be returned.

Prevent automatic OAuth grants for public clients (#30790)
This commit forces the resource owner (user) to always approve OAuth 2.0
authorization requests if the client is public (e.g. native
applications).

As detailed in [RFC 6749 Section 10.2](https://www.rfc-editor.org/rfc/rfc6749.html#section-10.2),

> The authorization server SHOULD NOT process repeated authorization
requests automatically (without active resource owner interaction)
without authenticating the client or relying on other measures to ensure
that the repeated request comes from the original client and not an
impersonator.

With the implementation prior to this patch, attackers with access to
the redirect URI (e.g., the loopback interface for
`git-credential-oauth`) can get access to the user account without any
user interaction if they can redirect the user to the
`/login/oauth/authorize` endpoint somehow (e.g., with `xdg-open` on
Linux).

Fixes #25061.

Improve oauth2 client "preferred username field" logic and the error handling (#30622)
Follow #30454
And fix #24957

When using "preferred_username", if no such field,
`extractUserNameFromOAuth2` (old `getUserName`) shouldn't return an

And fine tune some logic and error messages, make code more stable and

Enhanced auth token / remember me (#27606)
Closes #27455

> The mechanism responsible for long-term authentication (the 'remember
me' cookie) uses a weak construction technique. It will hash the user's
hashed password and the rands value; it will then call the secure cookie
code, which will encrypt the user's name with the computed hash. If one
were able to dump the database, they could extract those two values to
rebuild that cookie and impersonate a user. That vulnerability exists
from the date the dump was obtained until a user changed their password.
> 
> To fix this security issue, the cookie could be created and verified
using a different technique such as the one explained at
https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies.

To avoid potential risks (any bug in the template context function

`github.com/golang-jwt/jwt` v5 is bringing some breaking changes:

- standard `Valid()` method on claims is removed. It's replaced by
`ClaimsValidator` interface implementing `Validator()` method instead,
which is called after standard validation. Gitea doesn't seem to be
using this logic.
- `jwt.Token` has a field `Valid`, so it's checked in `ParseToken`
function in `services/auth/source/oauth2/token.go`
