Replaced individual environment-based server URL retrievals with a centralized ServerUrl utility. This change simplifies URL management and ensures a consistent approach across different services. Added validation for SSL configurations when using HTTPS.

Removed standalone ServerUrl and integrated with combined ServerUrl/ApiUrl module. Refactored codebase to use ApiUrl for public network accessibility and adjusted corresponding imports.

Renamed utils file for better readability and consistency. Updated all references to the new file name and added unit tests for ServerUrl and ApiUrl functionalities.

Move the reset of ServerUrl and ApiUrl to beforeEach in tests to ensure clean state before each test runs. Update example SSL_KEY_PATH and SSL_CERT_PATH to use relative paths for more portability.

Import the ApiUrl module and set the local URL in the setup function. This ensures the tests have the correct API endpoint configured.

Reordered import statements in `workspace-invitation.service.spec.ts` for improved code organization. This change ensures that dependencies are imported in a more logical sequence.

Included API_URL in self-hosting documentation for public endpoint configuration. This helps developers set up the correct URLs for API interactions in their self-hosted environments.

Removed protocol check logic from main.ts and enforced URL validation to require protocol directly in environment variables definition. This ensures consistent and secure URL formats throughout the application.

Add a new Bash script for generating self-signed SSL certificates, including a README with instructions. Supports customizable domain, root certificate name, and validity period, and integrates root certificate into macOS keychain.
