Fix mineral hold clamping on restore and re-assert Explore gate

- Raise the ship's mining capacity from build records before applying saved minerals, so holds above the base 250 cap survive load/jump-cut instead of being clamped away.
- Re-assert the EXPLORE story gate after blanket slot re-arming in SurfaceScene to prevent it coming back live pre-'Special Delivery'.
- Move ui_hover SFX from row/node hover to close-button hover in BuildWindow and ResearchWindow.
