Fix broken development routes and imports

Critical fixes:
- Update dev/app/api/test-email/route.ts to use new sendEmail API instead of deprecated sendEmail/scheduleEmail
- Fix dev/test-plugin.mjs imports to remove scheduleEmail reference
- Update dev/README.md examples to use new sendEmail pattern
- Replace templateId with template.slug throughout dev examples
- Add support for direct HTML emails in test route

The development routes now work correctly with v0.1.5 API changes.
