refactor: migrate remaining alert banners and error states to tokens

Migrate the last banners to the Alert component: ResetPassword success,
MessageContent connection error, and MemoryInfo storage-full errors. Tokenize
the Agents ErrorDisplay error state in place (icon badge, headings, message,
retry button) since it's a full error state, not a compact callout. Also
tokenize ResetPassword field-validation errors to text-text-destructive
(fixes the low-contrast dark:text-red-900).
