Add role and auth method info to users list (feature request)

[jeslinmx]

See above for rough mockup. Roles in muted text next to username; on right side, count of passwords, OTPs, and keys configured, and/or icons indicating which types of SSO have been setup for this user.

I have some Svelte experience, I can look into contributing PRs for this (and other similar lists where I feel that UX might be improved by surfacing more info at an overview level) when my time allows, if there is interest.
