migrate the signup and onboarding profile writes to sdk actions

The post-signup and onboarding writes (setPersonalDetails, upsertProfile,
overwriteSavedFeeds, setInterestsPref) move onto sdk actions over the pds
client, and the starter-pack and contact-import reads move to the lex
clients. Every upsertProfile call now writes a lex blob directly, so the
toLegacyBlobRef bridge has no remaining callers and is deleted.
