What's Fixed

1. Double-Encryption Bug ✅

Problem: API keys became corrupted when settings were saved multiple times, causing authentication failures.

Solution:

• ✅ Added automatic detection to prevent re-encryption
• ✅ Auto-repair of existing corrupted keys on plugin load
• ✅ One-time migration runs transparently
• ✅ No user action required

2. API V2 Compatibility ✅

Problem: Plugin was sending unsupported fields causing 500 Internal Server Errors.

Solution:

• ✅ Removed SubmittedContentType, IsHtmlContent, ReplyToEmail fields
• ✅ Made SenderName optional (only sent when not empty)
• ✅ Added default values for empty subject/message fields
• ✅ Full compliance with EnjinMel V2 API spec
