Implement logic to handle access token expiry

[birtony]

As per @rolsonquadras's comment, currently we have the following problem:

• Keep the page open for 25 mins without action
• Click on Vaults tab - shows loading screen with console error
  Error: agent wasm: code: 12008, message: failed to get VC wallet profile: failed to get value from main store: failed to get value from underlying store: failed to get encrypted document stored under a deterministic document ID: failed to retrieve document from EDV server: status code 401 was returned along with the following message: unauthorized

We need to come up with a solution that would redo the authentication flow once access token is expired instead of sending requests to the server with expired token, which would throw an error.

Probably we could add this check to any server call we make.
