Is your PR related to a specific issue/feature? Please describe and mention issues.

Closes #33 by supporting Bearer token authentication as well as a Cookie-based approach.

Now users can choose which authentication mode to use:

• cookie
• token

By default, token mode enables cookie-based storage, that keeps an auth token in the cookies available for both CSR and SSR requests without further code changes.

When custom storage is needed, users should define their own token storage handler in app.config.ts and implement custom logic based on the needs (Capacitor, Ionic, LocalStorage, etc)

Additional context

To work with token API also should be changed accordingly to return a proper JSON response, right now Login endpoint expects:

{
  "token": "token_value"
}

Checklist:

• Code style and linters are passing
• Backwards compatibility is maintained
• Requires documentation to be updated
