Update dns_czechia.sh
Update dns_czechia.sh
Refactor the Czechia/Zoner DNS API script to ensure stability and better user experience. Changes: - Replaced Bash-specific substitutions with POSIX-compliant code (fixes 'Bad substitution' errors on dash/sh). - Improved JSON payload construction to be more robust across different shell environments. - Updated hostname logic to correctly use "@" for apex domains. - Refined error reporting: API error messages are now captured and displayed in English. - Cleaned up internal debug messages and aligned them with acme.sh standards. - Optimized zone picking logic for faster matching in multi-zone setups.pull/6764/head
