Show full untruncated content in approval requests

Permission requests only ever displayed a summary that was hard-capped:
RiskClassifier.title() slices to 80 chars, and the iOS card used a lossy
compactSummary clipped to 8 lines. The full tool input was present on the
request but never shown, so a long Bash command, file path, or URL was cut
off with "…" and the user couldn't see what they were granting.

- Add RiskClassifier.detail(toolName:input:): the full, untruncated content
  (full command/path/url/query), falling back to the pretty-printed input so
  nothing about an unrecognized tool is hidden.
- Add JSONValue.prettyString() for indented, multi-line display.
- macOS ApprovalBar: render the detail in a bounded, scrollable, selectable
  monospaced block (shown only when it adds beyond the already-shown title).
- iOS ApprovalCardView: replace lossy compactSummary/lineLimit(8) with the
  full content in a bounded scroll view via JSONValue.approvalDetail.
- Tests: assert detail is full and untruncated, with pretty-input fallback.
