fix: BSR rank line now shows in BSR vs Units Sold chart

BSRRecord.market is stored as short codes ('DE', 'IT', etc.) from the
Excel file, but the chart was comparing against full names ('Amazon DE',
'Amazon IT', etc.) — causing bsrRecordsForMarket to always be empty and
the BSR line to never render. Added normalizeBsrMarket() to map short
codes to full names before filtering. Also removed the debug strip.
