Fix hydration

[cprecioso]

According to facebook/react#36169, we'll need to migrate to async scripts instead of defer

[greptile-apps]

Confidence Score: 5/5

Safe to merge — minimal, targeted fix with no risk of regression

The change is a two-attribute swap (defer → async) on third-party analytics script tags. Both attributes are well-understood browser primitives: async is semantically correct for independent analytics scripts that have no ordering constraints and don't depend on DOM readiness. The vite-ignore='' cleanup in the diff file removes an attribute that was never a real Vite directive (the valid Vite attribute is data-vite-ignore), so its removal is a harmless improvement. No application logic is affected.
