Mirrors Steelhead screens 1-3, 14-15. Loads preview on mount,
re-checks hard-blockers on commit. MOVE (n) button disabled when
hard-blocked OR required prompt blank — improvement over Steelhead's
silent disabled state (we show a tooltip listing reasons).
Inline 'Resolve' button next to each blocker. For rack-required,
fires a window CustomEvent ('fp-resolve-rack') the parent tablet
catches to open the Rack Parts sub-dialog.
Typed input rendering by input_type — text/number/checkbox/select/
datetime, plus support for time_hms and signature/photo (text input
for now; full upload widget in Sub 12c).
