Bridge No-Codes loadScreen, defaultVariables and custom action event (DEV-1188)

[SpertsyanKM]

Brings the No-Codes API from sandwich 7.10.1 (native iOS 6.13.0 / Android nocodes 1.10.0) into the RN layer.

DEV-1188

Changes

• Sandwich bump 7.9.4 → 7.10.1 (podspec + gradle).
• NoCodes.loadScreen(contextKey): Promise<NoCodesScreen> — load-before-present; the screen model exposes id, contextKey, defaultSelectedProductId and typed defaultVariables (kind: custom|product|selected_product|unknown, typed value + stringValue) with a defaultVariable(key, kind?) lookup mirroring the native SDKs. Presenting stays on showScreen (served from cache).
• New nocodes_custom_action event → optional onCustomAction(value) callback on NoCodesListener (optional keeps existing listeners source-compatible).
• TurboModule spec: new loadScreen method; iOS bridges via sandwich BridgeCompletion → promise, Android via Utils.getResultListener.

Verification

• yarn typecheck ✅, yarn test ✅ (10/10), eslint on the new file ✅ (repo-wide prettier debt untouched)
• Android codegen (generateCodegenArtifactsFromSchema) ✅ + :qonversion_react-native-sdk:compileDebugKotlin ✅ against sandwich 7.10.1
• iOS example build against pod 7.10.1 — running, will report in a comment

iOS verification status: pod update QonversionSandwich Qonversion resolves 7.10.1 cleanly in the example. The full example app build fails in the third-party fmt pod (consteval errors with the local Xcode toolchain) — pre-existing environment incompatibility of the RN example, unrelated to this diff (our target is never reached; fmt does not depend on SDK code). Android side is fully compiled: codegen + compileDebugKotlin against sandwich 7.10.1 ✅.

Review addressed: Android loadScreen wrapped in try/catch (uninitialized SDK rejects instead of crashing), ClientError added to NoCodesErrorCode + mapper, NoCodeEvent.payload union extended with QNoCodeCustomActionInfo, example Podfile.lock (sandwich 7.10.1) committed. Typecheck + Android compile green.
