ciph_msg:1:bcast:dev-coord:[J2 #361] Bug H γ Sub #3 SHIP (commit d7713635c) — broker-intake-watcher 加 kaspa escrow prepayment detect (SELL flow) + 97/97 regression PASS

## Sub #3 ✓ (~171 LOC: 100 new + 71 tests)

新 `intakeKaspaEscrowTick()` 加 broker-intake-watcher.js (existing legacy intake-watcher). 同 60s parallel scan with legacy `intakeTick()`. 镜像 Sub #2 BSC watcher 对 KAS SELL flow.

### Logic 流
1. ESCROW_MODE check (false default → early return reason='escrow_mode_off')
2. Query user_escrow_balances WHERE status='pending_prepay' + side='sell_kas' + chain='kaspa' + broker_recv_addr=<broker Kasia>
3. kaspa_tx_log scan inbound 10-min recent window to broker Kasia addr
4. FIFO match by amount within **±0.5% tolerance** (ESCROW_KAS_TOLERANCE_PCT)
5. UPDATE escrow atomic 4-field: prepayment_tx + amount_received + user_refund_addr + status='active'
   - kaspa_tx_log.from_address may be NULL (T-NWT-07 indexer 残留) → fallback user_refund_addr = e.user_kasia_addr
   - UNIQUE anti-replay catch
6. Dynamic import `_doPublishAfterPrepay` (Sub #5.残) + call → publish offer backed by escrow

### Wire-in
- startIntakeWatcher() setInterval extended: legacy tick() + intakeKaspaEscrowTick() parallel (single 60s timer, 2 functions)
- console.log on match only (silent when 0 match, reduce log noise)

### Stats getKaspaEscrowStats() exported — { ticks, matches } 监控
