Fix #3525: Make level name matching case-insensitive (#3535)

Browse Source 
Modified from_str() to perform case-insensitive comparison for all level names.
This allows environment variables and SPDLOG_LEVEL_NAMES to use uppercase or
mixed case level names (e.g., DEBUG, INFO, Warning) while maintaining full
backward compatibility with existing lowercase names.
