FED-76: Update LegacyDaoForwarder to perform migration of entries from old -> new format.
FED-76: Brought back all legacy DAOs from pre-commit cf204368aa7211e52fa6068a0f5b41ec64f911b0.
Updated all new DAOs with LegacyDaoForwarder: database entries of all types will be migrated to the new format on first use attempt.
Renamed Grant.scala -> Grant2.scala to avoid same-package class name conflict on imports.
