Pull request overview

This PR focuses on reducing user-perceived latency in the web app (route chunk preloading + loader cache revalidation), improving operational safety of MongoDB migrations under concurrent startup, and enabling additional compression/caching in the delivery stack. It also removes the queries field/metrics plumbing from the Account model across backend + generated clients.

Changes:

• Add preloadable lazy routes and wire hover/focus/touch preloading into navigation components.
• Make protected-route loaders return Zustand-cached data on warm navigations and revalidate in the background.
• Improve MongoDB migration locking/observability (advisory lock + TTL cleanup + better dirty/locked error surfacing) and add HTTP compression/caching changes.
