CertMate v2.1.2

Bug Fixes

Issue #82 — RFC2136 credentials file generated with wrong certbot key

Root cause: the RFC2136 credentials writer generated dns_rfc2136_nameserver, but certbot expects dns_rfc2136_server in rfc2136.ini.

Fix:

• corrected RFC2136 INI key generation in modules/core/utils.py
• added regression coverage in tests/test_issue82_rfc2136_config.py

Validation

• Full test suite passed: 166 passed, 9 skipped, 0 failed
• Release tag: v2.1.2
