- drop ClientPortal module, ClientTicket entity, ROLE_CLIENT and all couplings (Task, TaskDocument, User, Notification) back to an internal-only model
- migration drops client_ticket / user_allowed_projects / related FK columns and removes leftover external client accounts (would otherwise be promoted to ROLE_USER)
- remove client-portal frontend module, admin tickets tab, user portal section, portal nav item and portal/clientTicket i18n keys
- fix directory nav icon (invalid mdi:contact-multiple-outline -> mdi:card-account-details-outline)
- add 'make sync-permissions' target, wire it into install/db-reset and the prod deploy script
