setup local login on cms

[elfkuzco]

Rationale

This PR enhances the CMS by adding the functionality required to register/sign in users with a local authentication mechanism (password + username combination)

Changes

• add password_hash to user model, make id column primary key instead of idp_sub
• add table for creating/deleting refresh tokens
• set up local authentication provider on frontend
• use local tokens for testing

This closes #146

LGTM, I did not performed manual test but it looks very similar to what has been done on Zimfarm so I expect it to be ok, let's merge.

Going to need #149 review before merging as it's directly based on it because of the migrations they both introduce
