fix: histsync LID improvements — raw_id mapping, prekeys, keepalive j… (#304)

* fix: histsync LID improvements — raw_id mapping, prekeys, keepalive jitter, CDN DELETE

* fix: prekey pool strategy — 800 initial, top-up to 800 when below 200

- INITIAL_PREKEY_COUNT: 812 → 800 (rounded, matches WA Business ~812 from CDP capture)
- MIN_PREKEY_COUNT: 25 → 200 (replenishment trigger threshold)
- uploadPreKeysToServerIfRequired: top-up to INITIAL_PREKEY_COUNT instead of
  uploading a flat MIN_PREKEY_COUNT — restores full 800-key pool on each replenish
- handleEncryptNotification: same top-up logic (INITIAL_PREKEY_COUNT - count)
  so server notification path also restores to 800, not just adds 200

uploadPreKeys(5) in error recovery path intentionally left unchanged.
