- Fix column display for Desjardins-style quoted CSVs (apply preprocessQuotedCSV in header loading)
- Fix column mapping disappearing on back-navigation (generate synthetic headers when hasHeader is false)
- Fix auto-detect picking account number as amount (exclude constant-value columns, treat 0 as empty in debit/credit detection)
- Use category type instead of amount sign for dashboard pie chart and recent transactions

Analyzes imported CSV files to automatically detect delimiter, header,
date format, column mapping, amount mode, and sign convention. Excludes
running balance columns from amount mapping via consecutive-row math.
