dnsapi/deploy: remove POSIX character classes from sed/grep patterns
Solaris /usr/bin/sed and /usr/bin/grep parse [[:space:]] etc. as a
literal bracket set and silently mis-match. Replace with [ ]* for
JSON matching, a printf-tab bracket for user-input trimming, and
[0-9] for digits; also drop GNU-only sed -r/-E in rage4, selfhost
and selectel, and reuse _strip_blank_lines in byteplus_alb.
- Added _get_root() helper function for proper zone detection
- Fixed zone ID extraction to match dns/auth_zone/* pattern
- Added _infoblox_rest() wrapper for API calls with proper auth
- Improved error handling for authentication failures
- Added support for wildcard certificates (multiple TXT records)
- Filter by exact txtvalue when deleting records
- Follow acme.sh best practices and conventions
Tested with:
- Standard domain certificates
- Wildcard certificates (*.domain.com)
- Multiple subdomains
- Staging and production Let's Encrypt
