Add standalone mode with @simpleworkjs/orm-backed user/host stores

- Add standalone.enabled config flag to switch between LDAP+SSO and ORM-backed backends without changing the production code path - New ORM models: StandaloneUser (uid, passwordHash, sshPublicKeys, groups) and StandaloneHost (slug, displayName, kind, metadata) - user_file.js and hosts_file.js implement the same interfaces as the LDAP client and accessibleHosts() respectively - models/user_ldap.js and utils/access.js become conditional facades that delegate based on conf.standalone.enabled at require time - Zero changes to ssh_server.js core logic, bridge.js, key_inject.js, tui_picker.js, or any other consumer - Fix ssh_server.js: use ?? instead of || for listenPort (0 is falsy) - Fix ssh_server.js: register session listeners before awaiting audit.create() so client exec/shell requests aren't rejected - Patch StringField.toSequelize() and IntegerField.toSequelize() to pass through primaryKey (the ORM's UUIDField already does this) - 47 tests pass (24 existing + 15 new unit + 3 existing integration + 5 new standalone integration) - Defaults to SQLite; any Sequelize dialect works via conf.orm Co-Authored-By: Claude <noreply@anthropic.com>
