feat: deploy the app on the /rare-basket/ context
- configure the context path in application.yml
- configure the context path in proxy.conf.json
- configure the context path (baseHref) in angular.json, that will automatically set it in the generated index.html file
- inject and append the base href in the authentication service to pass it as redirect uri to keycloak
- configure the redirectUris of the realm of keycloak in rare-basket-realm.json
- update the authentication documentation
- use relative paths rather than absolute paths to get resources from the server, so that the base href is always prepended
- fix the title of the app
