feat(#690): add collapsible evidence panel to node clock skew card

Renders recentHashEvidence from the API in a collapsible details section.
Each hash shows observer count, median corrected skew, and per-observer
breakdown (raw, corrected, observer offset). Includes calibration summary
line and plain-English severity reason at top.
