QQQ core's standard permission suffix is hasAccess
(PrivatePermissionSubType.HAS_ACCESS) and the assistant base already
follows the naming rule, so the permission stays assistant.hasAccess,
matching the sql-workbench rename. Drops LEGACY_ACCESS_PERMISSION and
updates README, CHANGELOG, UPGRADE.md and NamingTest. Table, PVS and
key-type renames are unchanged.
