Enhance OIDC Authentication: Support Dynamic Redirect URLs, Authentication State in Cookies, and Bearer Token Handling

[modoulo]

Issue Description:

Currently, the OIDC authentication flow is limited due to a fixed redirectURL, preventing dynamic redirection for multiple applications. Additionally, applications without frontend authentication logic struggle to persist authentication state, and there is no support for Bearer tokens in HTTP headers.

Proposed Solution:

1. Support Multiple Applications with Dynamic Redirects:

Introduce a new configuration field, AuthorizedRedirectDomains []string, allowing users to define a list of authorized domains.
If an incoming request matches one of these domains, the appropriate redirectURL will be applied dynamically.

2. Persist Authentication State in Cookies:

Store authentication state in cookies to enable OIDC authentication for frontend applications without requiring custom authentication logic.

3. Support Bearer Tokens in Headers:

Allow authentication via Bearer tokens in HTTP headers, enabling backend services and microservices to authenticate requests without requiring cookie-based sessions.
