feat(debug): add debug read with CSV export

- Parse F1 debug data via family-independent temp formula
  (bits 4-14 scaled by 2**(i-8), sign at bit 0)
- Save sensor+debug temps side-by-side to debug_info.csv
- Wire READ DEBUG button in StatusActionsPanel
- Rename ReplayChart → RunChart; move into GraphTab
- Extract PanelBox/SectionTitle/PanelSlider in ReadoutPanel
  to cut ~300 lines of duplicated styling
- Add rightRailWidth token to Theme for consistent rail sizing
- Wrap ReadoutPanel in ScrollView so Thresholds card stays
  reachable when E-C delta rows appear
