v1.9.0 Beta 7

Tuya Cloud login fix for S1 Pro

Includes JerryVDP's fix from PR #111: the Tuya API returns the RSA public key as a decimal string (pure digits, no a-f characters). The _is_hex detection now correctly identifies this, so the key size is computed from the modulus bit length — fixing the USER_PASSWD_WRONG error.

Changes since Beta 6

• Improved _is_hex() to distinguish decimal vs hex public keys (#111 by @JerryVDP)
• Removed debug logging noise from password encryption
• Fixed test suite for the new decimal key handling

Testing

@JerryVDP please confirm this works for your S1 Pro!
