fix(apple/ios): the ACTUAL type-checker bomb was pointerSection's footer ternary chain

4f3cd24 split the wrong expression — act's log masking hid the real line number.
The unmasked retry pinpointed it: the pointerSection footer, a ten-segment
string + chain with an isPad ternary nesting four more, evaluated inside the
ViewBuilder. Moved the copy into a plain computed String built with +=
statements (linear to type-check); no text change. The two remaining 5-6
segment chains in Settings are compiled by the passing macOS slice, so they
are proven cheap.
