Add ticket_title_max / ticket_content_max / ticket_reply_max to the users/ticket schema (PHP + SPA) with clamped TicketSettings readers. All write paths (front REST, admin REST, note REST, native admin page) and front-end maxlength/counters now read the configured limits. Remove the hardcoded TICKET_CONTENT_MAX constant.
