Parity markup and tolerance configurable as % or flat £

Browse source 
- config: parity_markup_value/_unit + parity_tolerance_value/_unit
  (pct|gbp), legacy *_pct keys still read as fallback
- expected rate = newbook + £X or newbook × (1 + X%); breach test uses
  the tolerance in its own unit
- Settings parity tab: unit selects + live worked example line
- Parity Alerts tab: unit-aware description, badge now shows £ deviation
  alongside %
