feat: Payment Compliance Pack — Semgrep + CodeQL + State Machine + Schema

Ausfuehrbares Pruefpaket fuer Payment-Terminal-Systeme:

1. Semgrep-Regeln (25 Regeln in 5 Dateien):
   - Logging: Sensitive Daten, Tokens, Debug-Flags
   - Crypto: MD5/SHA1/DES/ECB, Hardcoded Secrets, Weak Random, TLS
   - API: Debug-Routes, Exception Leaks, IDOR, Input Validation
   - Config: Test-Endpoints, CORS, Cookies, Retry
   - Data: Telemetrie, Cache, Export, Queue, Testdaten

2. CodeQL Query-Specs (5 Briefings):
   - Sensitive Data → Logs
   - Sensitive Data → HTTP Response
   - Tenant Context Loss
   - Sensitive Data → Telemetry
   - Cache/Export Leak

3. State-Machine-Tests (10 Testfaelle):
   - 11 Zustaende, 15 Events, 8 Invarianten
   - Duplicate Response, Timeout+Late Success, Decline
   - Invalid Reversal, Cancel, Backend Timeout
   - Parallel Reversal, Unknown Response, Reconnect
   - Late Response after Cancel

4. Finding Schema (JSON Schema):
   - Einheitliches Format fuer alle Engines
   - control_id, engine, status, confidence, evidence, verdict_text

+# CodeQL Query: Sensitive Data to Logs
+
+## Ziel
+Finde Fluesse von sensitiven Zahlungsdaten zu Loggern.
+
+## Sources
+Variablen, Felder, Parameter oder JSON-Felder mit Namen:
+- `pan`, `cardNumber`, `card_number`
+- `cvv`, `cvc`
+- `track2`, `track_2`
+- `pin`
+- `expiry`, `ablauf`
+
+## Sinks
+- Logger-Aufrufe (`logging.*`, `logger.*`, `console.*`, `log.*`)
+- Telemetrie-/Tracing-Emitter (`span.set_attribute`, `tracer.*)
+- Audit-Logger (wenn nicht maskiert)
+
+## Expected Result
+| Field | Type |
+|-------|------|
+| file | string |
+| line | int |
+| source_name | string |
+| sink_call | string |
+| path | string[] |
+
+## Mapped Controls
+- `LOG-001`: Keine sensitiven Zahlungsdaten im Log
+- `LOG-002`: PAN maskiert in Logs
+- `DATA-013`: Sensitive Daten in Telemetrie nicht offengelegt
+- `TELEMETRY-001`: Telemetriedaten ohne sensitive Zahlungsdaten
