feat(myai-data): cleanup migration removes email.* and ai.* templates; update CLAUDE.md

- Add DeleteMigratedTemplates migration: removes all email.* and ai.*
  rows from myAi.Templates (now owned by emailApi.EmailTemplates and
  cvMatcher.AiPrompts respectively)
- CLAUDE.md: add email-api-data to solution layout; add emailApi schema
  to database schemas table; add email-api-data EF CLI migration command;
  note cv-matcher-api no longer runs MyAi migrations
