Summary

Fix hexadecimal address parsing in config set. Previously, an input such as address=0x10 was converted to the decimal string 16, then interpreted as hexadecimal 0x16.

• Preserve hexadecimal digits and leading zeros in EEPROM addresses.
• Support both 0x and 0X prefixes.
• Keep existing numeric conversion for other configuration values and parameters.
• Add four regression tests covering address formats, numeric parsing, and invalid input.

Fixes #46
