refactor(ts): convert SearchFilterPanel, RecentlyDeletedBillsDialog, BillRulesManager to TSX (B15)

SearchFilterPanel (presentational props), RecentlyDeletedBillsDialog (Bill[],
days_left cast, formatUSD on Dollars), BillRulesManager (MerchantRule/RuleGroup,
reduce<Record<number,RuleGroup>> with `?? (acc[key]=…)` to satisfy
noUncheckedIndexedAccess). typecheck 0, build green.
