fix: cropper mime bug + loadSiteIdentity crash + logo|name header

1. applyCrop() — mime variable was declared INSIDE toBlob callback
   but used as an argument to toBlob() (outer scope) → ReferenceError.
   Fix: declare _mime, _quality, _ext BEFORE out.toBlob() call.

2. loadSiteIdentity() — crashed when identity section had no rows
   (data was null/non-array). Fix: safe Array.isArray guard + catch.

3. Header logo: show logo image + | + site name side by side
   when logo is configured (was showing one OR the other).
