Align React Native SDK with OMS Wallet 0.2.0

[tolgahan-arikan]

Summary

• upgrade the wrapper to oms-wallet-swift-sdk and oms-wallet-kotlin-sdk 0.2.0 and rename the internal TurboModule/pod target accordingly
• align the public API around OMSWallet, exported Networks, fixed OMS relay OIDC providers, custom provider redirects, structured session auth, stable OMS errors, fee selectors, and transaction status resolution
• update the bare, Expo, and Trails examples together with focused bridge tests
• add yarn verify and ensure the standalone Expo check installs a tarball from the pending local source
• replace stale API and release documentation

Breaking API changes

• OMSClient becomes OMSWallet
• OidcProviders becomes fixed OmsRelayOidcProviders values; custom providers require providerRedirectUri
• wallet, signing, transaction, and indexer methods use exported Network values instead of string chain IDs
• signature verification methods are named isValidMessageSignature and isValidTypedDataSignature
• redirect completion returns { type: "completed", result }
• session state exposes structured email or OIDC auth details

Verification

• yarn verify
• yarn expo-example:install && npm --prefix examples/expo-example run typecheck
• Android bridge compilation against the locally published Kotlin 0.2.0 artifact
• full unsigned iOS Simulator build against the local Swift 0.2.0 pod

Release prerequisite

Keep this PR in draft until oms-wallet-kotlin-sdk:0.2.0 is available from Maven Central and oms-wallet-swift-sdk 0.2.0 is available from CocoaPods. The example lockfiles intentionally remain on the currently published native dependencies until those artifacts can be resolved normally.
