fix(signal): align Signal Protocol handling with WABA Android behavior (#257)

Browse Source 
7 corrections based on reverse-engineering of WhatsApp Business Android:

1. resolveCanonicalJid: PN→LID resolution for transaction lock keys (prevent race conditions)
2. Retain PN session during LID migration (avoid No Session errors)
3. Delayed PreKey deletion with 5-min grace period (prevent Invalid PreKey ID races)
4. Surgical session cleanup: only delete the specific corrupted device, not all devices
5. Identity dual storage: save identity key in both LID and PN addresses
6. MAC error cooldown reduced 10s→1s (faster recovery, aligned with WABA)
7. Allow session recreation on first retry (retryCount >= 1 instead of > 1)

* fix: remove unused jidDecode import from decode-wa-message.ts
* fix: add try/catch to delayed PreKey deletion to prevent unhandled rejection

The setTimeout async callback in removePreKey could cause unhandled promise
rejection if the keystore was destroyed (connection closed) before the
5-min grace period expired.
