chore: upgrade the Expo Web3.js templates to SDK 57.0.19

[beeman]

expo-web3js-paper moves from SDK 55 to 57, so all three Expo Web3.js templates now suppress the dev-menu bottom sheet and the onboarding popup through the expo-dev-client plugin entry, and dev builds open straight into the app. SDK 56 is skipped and the floor is 57.0.19, since SDK 55 with Hermes V1, all of SDK 56, and SDK 57 before 57.0.9 carry a memory regression that hits react-native-worklets and react-native-reanimated — every template here uses both.

Paper's SDK 57 migration

Two breaking changes needed source work. SDK 56 forbids importing @react-navigation/* directly, so Button comes from expo-router/react-navigation and the three dependencies are gone. Expo Router also widened navigation colors from string to ColorValue, which made adaptNavigationTheme resolve to the wrong overload and produced four type errors; the theme bridge now casts the router themes to the adapter's own parameter type. Navigation was separately being handed an MD3 typescale as fonts where it expects { fontFamily, fontWeight }, so it keeps its own font styles. React Compiler is enabled, matching the other two templates.

Fixes surfaced by the upgrade

react-native-reanimated was pinned as ~4.5.1, which resolves to 4.5.5 — a version expo-doctor rejects for this SDK. It now pins to exactly 4.5.1 in all three templates, not just paper.

expo-web3js-wallet never declared expo-constants, a required peer of expo-router. expo-doctor warns this can crash outside Expo Go, because native autolinking will not pick up a transitive copy.

Paper also drops a dead react-native-snackbar doctor exclude — it renders react-native-paper's own Snackbar and never depended on that package. Dependency floors record the versions each template was verified against, and every template declares the expo-status-bar plugin.

Verification

Each template passes tsc --noEmit, expo lint, prettier --check, expo-doctor (21/21) and a full Android bundle export. solana-mobile templates check reports the template artifacts up to date.

Two items left out on purpose. The repo-root prettier --check . flags scripts/shared/image-utils.tsx, which is unmodified here and fails on main too — the root declares prettier ^3.6.2 while the install resolves 3.9.6. expo-web3js-minimal carries an expo-image dependency it never imports, and dropping dependencies during an SDK upgrade risks removing a required peer.
