The pasteboard UTType constants become edition twins — Pro stops claiming ownership it doesn't have

Latent since the m7 split: base's Info.plist exports the three family
pasteboard types (cards, lanes, clipboard) and Pro's imports them, but
the shared constants declared all three UTType(exportedAs:) — a claim
of ownership the system checks against the running app's plist. In Pro
that claim is false, and the first touch (the clipboard type, via the
launch sweep) raised a runtime fault that blocked board loading under
the debugger.

EditionAbout's twin-file pattern, applied to an initializer: the
constants move to Kanban/App/EditionTypes.swift (exportedAs) with a
KanbanPro/Edition/EditionTypes.swift twin (importedAs, identifiers
verbatim); project.yml excludes base's copy from Pro. Type identity is
the string, so payloads cross editions unchanged. Verified: Pro
fixture launch opens the board with zero UTI warnings; both suites
green; verify-editions 30/30.
