Subject: [PATCH] test: add obfuscation round-trip tests, fix i18n module
 import

- 7 passing tests verify client-server compatibility:
  * Handshake obfuscation round-trip (correct key recovers session_id)
  * Wrong key produces garbage (prevents unauthorized probes)
  * Data packet obfuscation round-trip
  * Deterministic derivation (same key = same secrets)
  * Different keys produce different secrets
  * Legacy API consistency
  * Padding range validation (100 random keys)

- Fixed test module import path to use crate::crypto::obfuscation::*
- Added i18n.js module for GUI localization
