Subject: [PATCH] perf: pass storage to tryFallbackAccounts to skip redundant
 disk read

The fetch handler already loads storage at the start of every request.
tryFallbackAccounts was reloading it from disk unnecessarily. Now
accepts an optional existingStorage parameter to reuse the caller's
copy.
