Replace go-imap library with custom IMAP client, simplify CV layout styles, bump vite, move SEED_DB to backend

- Rewrite email_imap.go to use a minimal hand-rolled IMAP client instead of go-imap/go-message,
  for better compatibility with Outlook's non-standard responses
- Consolidate and simplify CVLayout.vue CSS overrides
- Bump vite from 7.1.11 to 7.3.2
- Move SEED_DB env var from nginx to backend in dev compose
- Add /app/src/wasm volume exclusion in dev compose
