Add AES-128/192/256 support to secured packet builder (v1.6.0)

- Bundle aes-js as aes-bundle.js (standalone aesjs global), precache in SW (v7)
- Add AES-CBC (zero IV, 16/24/32B) + AES-CMAC (SP 800-38B, 8-octet) helpers
- genSp(): algorithm dispatch, AES counter hard-block (b5b4 = 10/11 per Rel-18)
- Cross-checked AES vectors against pySim OtaDialectSms.encode_cmd
- Docs: AES + 3DES deprecation, fix stale SPI1 value table
