Continuity Frontier - beta 3 interface fixes

Keeps one Field Overview shortcut above the inventory/JEI area. Crew registration, clones and research remain accessible inside Operations.

Blocked pages now show the actual prerequisite or permission reason inside the panel, including campaign registration, team mismatch, clone recovery and campaign failure. Diagnostic panels are read-only and do not bypass research or machine permissions. All explanations follow the selected pack language.

The exact module passed 197 Java domain test programs. Client startup was observed, and the pack author reported that the menus work correctly in game. This is scoped interface acceptance, not a full survival campaign playthrough.

Requires matching Containment Frontier beta 3 pack data. The internal module version remains 0.5.0-dev. Previous submitted files are preserved.
