feat(sql): Add target and host history tables to session recording

This adds four columns to the `recording_session` table which are
foreign keys to the `iam_scope_hst`, `target_ssh_hst`,
`host_history_base`, and `host_catalog_history_base` tables. The foreign
key to the `iam_scope_hst` table references the project scope of the
target at the time of the recording.
