Filament's sanitizer strips data-id, data-label and data-char from
mention spans, breaking both display (unstyled @mention) and editing
(@-only shown in RichEditor). Register a package-scoped sanitizer that
explicitly allows these attributes on span elements.
Also fix double-replacement bug in renderBodyWithMentions() where both
the rich-editor regex and str_replace fallback could run on the same
mention, producing nested styled spans.
Update all tests to use new form state paths (commentData.body,
editData.body, replyData.body) instead of removed public properties.
Remove searchUsers() tests (method replaced by MentionProvider).
Add BladeUI Icons service providers to TestCase for RichEditor views.
