fix: Tolerate diacritic/case/whitespace mismatches in Person column matching

- Add canonical_member_key() in match_payments.py to normalize names via
  NFKD + lowercase + whitespace-collapse before ledger lookup; resolves
  payments attributed to e.g. "Maria Maco" to canonical "Mária Maco".
  Emits logger.info when a non-canonical cell is rescued so sheet typos
  are visible in logs without losing the payment allocation.
- Extend group_payments_by_person() in app.py to accept member_names and
  re-key raw-payment groups under the canonical attendance-sheet name so
  the modal's Raw Payments debug section also finds the row correctly.
- Add raw payments collapsible section to member detail modal in adults.html
  and juniors.html for debugging payment attribution issues.
- Remove 4 obsolete tests targeting routes /fees, /fees-juniors, /reconcile,
  /reconcile-juniors that no longer exist; add test_match_payments.py
  covering canonical key equivalence and reconcile() tolerance end-to-end.
