Jotai Cold Start SSR

Cold start optimization pattern for OneKey native app. Analogous to web SSR hydration — previous session's atom values are persisted to MMKV, pre-read at startup, and used as initial atom values so the first React render displays cached data immediately without waiting for network.

Currently supported: Native (iOS/Android) only. Desktop/Web/Extension support planned.
