Update dns_czechia.sh

dns_czechia: fix syntax errors and API payload format

- Fix missing 'done' in for-loop within _czechia_pick_zone
- Correct variable naming (use _fd_input instead of _fulldomain)
- Update hostname extraction to correctly send "@" for apex domains
- Fix "Invalid domain" error by normalizing zone names in API calls
