ui/phase-17: ship-class CRUD without calc

Phase 17 lights up the ship-class table and designer active views,
extends the order-draft pipeline with createShipClass and
removeShipClass commands, and projects pending Save/Delete actions
through applyOrderOverlay so the table reflects the player's
intent before auto-sync lands. The plan is corrected in the same
patch: per game/rules.txt, ship classes are designed once and
cannot be edited — the engine has no Update command, so the UI
exposes only Create + Delete.
