Backend changes add a tickets relationship to lines and preload tickets (ordered by updated_at) when fetching stations. The frontend now displays ticket information in CardLine, adds ticket history and management (create, update, close, issue) in ModalTerminal, and introduces new types for tickets. Various UI improvements include consistent button font weights, port name normalization, and enhanced log/tooltips. Obsolete takeover logic was removed from App and ModalTerminal.
