appview,lexicons: atprotate the mentions & references

Storing references parsed from the markdown body in atproto record and
DB. There can be lots of reference types considering the from/to types
so storing both as AT-URIs

Using `sql.Tx` more to combine multiple DB query to single recoverable
operation.

Note: Pulls don't have mentinos/references yet
