Improve the resend confirmation flow by:
- Consolidating multiple status messages into a single generic response
- Adding HTML support for the result message
- Moving the instruction text after the message display
- Simplifying the PHP logic by removing redundant checks
- Making the messaging more privacy-conscious by not revealing email
existence
- Adding a link to sign again in the result message
The changes follow the project's minimal PHP philosophy while improving
user experience and security.
