[IDM-172] - feat: generate passport

[kiremitrov123]

Description

This PR introduces the use of the recently implemented service to generate a passport — a JWE token that encapsulates the list of plans the viewer is entitled to. The passport is now stored in local storage and will be utilized by the media metadata endpoint.

Context:
The passport serves as a critical trust token for seamless communication with various services, ensuring the viewer's entitlements are recognized. While it is currently used by the media metadata endpoint, future enhancements will expand its usage across additional services, enabling more secure and efficient data retrieval.

In subsequent PRs, we will implement mechanisms to refresh the passport and leverage it further for media playback and other related functionalities.

Steps completed:

According to our definition of done, I have completed the following steps:

• Acceptance criteria met
• Unit tests added
• Docs updated (including config and env variables)
• Translations added
• UX tested
• Browsers / platforms tested
• Rebased & ready to merge without conflicts
• Reviewed own code
