feat(api): enhance OIDC redirect URI handling in service and tests (#1618)

- Updated `getRedirectUri` method in `OidcAuthService` to handle various
edge cases for redirect URIs, including full URIs, malformed URLs, and
default ports.
- Added comprehensive tests for `OidcAuthService` to validate redirect
URI construction and error handling.
- Modified `RestController` to utilize `redirect_uri` query parameter
for authorization requests.
- Updated frontend components to include `redirect_uri` in authorization
URLs, ensuring correct handling of different protocols and ports.

## Summary by CodeRabbit

* **New Features**
* Stronger OIDC redirect_uri validation and an admin GraphQL endpoint to
view full OIDC configuration.
* OIDC Debug Logs UI (panel, button, modal), enhanced log viewer with
presets/filters, ANSI-colored rendering, and a File Viewer component.
* New GraphQL queries to list and fetch config files; API Config
Download page.

* **Refactor**
* Centralized, modular OIDC flows and safer redirect handling;
topic-based log subscriptions with a watcher manager for scalable live
logs.

* **Documentation**
  * Cache TTL guidance clarified to use milliseconds.

* **Chores**
* Added ansi_up and escape-html deps; improved log formatting; added
root codegen script.
