update recipe flags on zimfarm

[elfkuzco]

Rationale

This PR adds functionality to the UI to update flags responsible for recipe metadata from the CMS. During book promotion actions, if there are actions to update title metadata, UI loads recipe details and informs user to make corresponding changes to the zimfarm recipe that created the book

Changes

• prompt user to update appropriate flags that are responsible for the metadata on zimfarm
• add methods to authenticate with zimfarm in cms auth store
• upload base64 blobs that are responsible for Illustration metadata to zimfarm before applying the patch with the returned URL

This closes #333
