Include plan alias in token information

[dpsutton]

We want to include plan alias in the token information so that we can use it in the upsell badging.

See
https://github.com/metabase/harbormaster/pull/4993/commits/462da5a91c33f2a7662ed15de1ac83b99da2c859 for the shape. Just a string on the key :plan-alias.

This is already the case. The token-status setting is visible to admins. We only show the upsell information to admins, so that information is already on the FE.

❯ http get "localhost:3000/api/session/properties" Cookie:$SESSION -pb | jq '."token-status"."plan-alias"'
"internal"

If you don't see it yet, add

To your deps.edn file under the :dev alias.

And perhaps we should also document it in the malli schema
