refactor(features): regroup TicketWorkspaceRail props into 8 bundles

Collapse the 38-prop flat interface (deferred from Wave 5.5) into 8
named bundles plus 2 primitives. Each bundle maps to one feature
area: intake, nextActions, similarCases, packs, kits, favorites,
runbooks, personalization. DraftTab shell, rail internals, and the
test suite all updated in lockstep; consumer behavior is unchanged.
