Security solution - OAuth2 github

[LinusWestling]

1. Add Dependencies: Add spring-boot-starter-oauth2-client to your pom.xml.
2. Security Configuration: Create a SecurityConfig to protect your /api/** and /ui/** routes and enable .oauth2Login().
3. User Mapping: Create a service to map a GitHub user (e.g., octocat) to your internal Actor and assign them a Role (like ADMIN
   or HANDLER).
4. Properties Setup: Add the GitHub registration settings to application.properties.
