Added authentication method selection in integration setup

[SagarGi]

Description

This PR introduces the initial implementation for supporting OIDC-based connections to integrate with OpenProject for backend-to-backend requests.

Key updates in this PR include:

• Adding a UI option for OIDC-based authorization.
• Enabling automatic connection when OIDC authorization is selected, and the Keycloak configuration (with proper token-exchange setup) is properly set up.
• Partially hiding the OpenProject UI and displaying an error message for non-OIDC users when OIDC-based configuration is enabled.
• Also admin is allowed to switch between both oidc and ouath2 based authorization through UI

NOTE: Error handling is not included in this iteration. Scenarios such as incorrect Keycloak setup, invalid tokens, or other issues will be addressed in a subsequent iteration.)

TODO STILL:

• fix regression for php and vue unit tests due to new changes
• add new php unit tests
• add vue UI unit tests(@SagarGi In progress)
