⚡️(frontend) add trailing slash on the /me endpoint call

The `/me` endpoint was called without a trailing slash, so every
request was going through a 301 redirect before hitting the actual
endpoint.

This endpoint is called by every user at least once per session, so
based on the logs, avoiding the redirect should cut the volume of
requests hitting it by around 10%.
