Make the outer accordion grouping in TransactionList granularity-aware
instead of hardcoded months. TransactionList accepts a granularity prop
(weekly/monthly/quarterly/yearly, default monthly); ReportViewer passes
the report's granularity so a weekly report buckets transactions by ISO
week, quarterly by quarter, yearly by year. Expense page keeps monthly
grouping. Add periodKey/periodLabel/groupByPeriod/toPeriodGranularity to
src/common/utils/transactions.ts and drop the dead groupByMonth/
GroupedMonth helpers.
