feat(fetchboa): bank-truth reconciliation v2 — returns, redeposits, ACH confirmation (#73)
* feat(fetchboa): v2 return/redeposit-aware reconciliation (#66)

The two-code 475/255 filter missed every return on the Jan-Jul statement
(29 ARP refer-to-maker credits, 24 electronic return credits, and the
redeposit cycles), leaving 5 paid-then-returned checks stuck at Cleared
($5,256.62, vendors unpaid). Rewrite fetchBoaTransactions around a pure
reconciliation module (src/boaRecon.js) covered by node:test:

- BAI transaction-code event map (only 475 = check paid is confirmed;
  remaining codes pend the enumeration replay) with a description-text
  fallback classifier for ARP refer-to-maker, return-of-posted-check
  (check-numbered and electronic) and ACH DES:PAYMENTS formats. Unknown
  check-shaped transactions are logged and counted, never dropped.
- Matching on check number AND amount over all candidates; wrong-amount
  or collapsed-number postings fall back to a unique exact-amount match
  within checks issued in the last 120 days; ambiguity means unmatched
  with no write.
- Transitions always set BOTH status and clear_status (the missed
  returns slipped through the divergence between them). clear_status is
  bank truth: returns apply even to Cleared records, a second paid debit
  on a Returned check is a redeposit back to Cleared, and a return on a
  voided check is terminal voided-and-bounced. Every applied event is
  appended to a history list; identical replayed events are noops.
- Optional {fromDate, toDate} replay payload (strictly validated) for
  gap replays and the BAI-code enumeration runs; default stays
  yesterday.
- Each run writes a boa_recon#<runDate> summary item (90-day TTL) with
  per-event counts, unmatched check numbers/amounts, and unknown codes;
  unmatched/unknown also console.error (Slack alerting is #71).

ACH transactions are classified but not yet acted on; bank-confirming
ACH lands with #69.

* feat(ach): bank-confirm ACH, drop CSV-date auto-clear (#69)

processPaymentCsv auto-cleared ACH the moment send_payment_on passed,
but the bank disagrees often enough to matter: settlement lags the send
date by up to 8 days, settled ACH can bounce and re-debit (Uline
$19,281.12, Heights $10,000.00 on the 5/26 overdrawn week), and voided
ACH that settled anyway returned via electronic credits invisible to a
Check-only feed. Move ACH to bank confirmation:

- processPaymentCsv: ACH rows keep their Stampli status; the send-date
  auto-clear is removed. The bankConfirmed protection is unchanged, so
  bank-cleared records still cannot be moved backward by the CSV.
- fetchBoaTransactions scans all payments (method filter dropped) and
  processes ACH CCD lines: match by stored pmt_id first (reversals
  reuse the original PMT id), then by the Stampli payment number
  embedded in PMT INFO (internal spaces stripped, amount must agree),
  then vendor + exact amount within send_payment_on -2..+14 days.
  Settled debit -> Cleared/Cleared with dates, pmt_id persisted on the
  record; credit reusing the pmt_id (or a unique same-amount return
  credit against a bank-confirmed ACH) -> clear_status=Returned +
  returned_date + history event. Ambiguity is unmatched, no write.

Existing DDB ACH records already Cleared by the old auto-clear are
unaffected: bank confirmation is additive and the CSV path never moves
a record backward.

Handler event contract extended (optional fromDate/toDate); cross-family
review required before merge.

* fix(fetchboa): close review findings — coverage gap, matcher corroboration, replay identity (#66)

Security-review gate (detector fan-out + verifier + GPT-4.1 cross-family)
blocked on F6 and confirmed six lower findings; all are closed here.

- F6 (HIGH): the default run now queries a trailing 3-day window
  (today-3..today-1) so the Monday run covers Friday-Sunday postings the
  previous-day cadence silently skipped. A per-run staleness sweep flags
  never-bank-confirmed payments (ACH > 16 days, checks > 60 days) in the
  summary and via console.error.
- F2: replay identity is {event, date, amount} — bankRef excluded (feeds
  omit/reformat it between runs); a paid event dated on/before the
  latest return in history is a replayed original, never a redeposit;
  rows without a valid valueDate are routed to unmatched instead of
  being applied under a substituted date; within a day, debits sort
  before credits.
- F1: a check-number match with the wrong amount no longer falls
  through to the amount fallback (altered-check/collapsed-posting is a
  human-review case); the amount fallback requires digit-subsequence
  corroboration between posting and candidate numbers; check_return
  fallback requires a bank-confirmed candidate.
- F4: the ach_return amount fallback requires cleared_date within 45
  days before the credit; an unattributable PMT id is an unmatched
  alert, never an amount guess.
- F5: the pmt_id rung requires amount equality; mismatch is the
  partial-reversal human case.
- F3: vendor prefix matching requires >= 10 normalized chars (short
  names must match exactly); candidates with a conflicting stored
  pmt_id are excluded; vendor+amount matches are audit-logged.
- F7: payment writes are conditioned on the snapshot's
  status/clear_status and retried once against a fresh read; residual
  conflicts are counted, not silently interleaved.
- F9/summary bounds: run summary pk is append-only
  (boa_recon#<from>_<to>#<runAt>); unmatched list capped at 50, unknown
  codes at 20 keys/16 chars, stale list at 50 (full counts kept).
- ReDoS: description bounded to 500 chars before classification;
  CHECK/embedded-number regexes use bounded quantifiers.
- FBOA2-1: both BoA res.json() parses are wrapped so a malformed 200
  throws a status-only error and cannot leak a body snippet.

Handler event contract extended (optional fromDate/toDate); cross-family
review required before merge.

* fix(boaRecon): add method=Check filter to matchElectronicReturn

Electronic returns only apply to checks, but the matcher was not
filtering by method, so an electronic return could incorrectly
match against a same-amount, bank-confirmed ACH record.
