ci: simplify iOS workflow caching and drop redundant prebuild workflow

- Remove standalone ios-runner-prebuild.yml (redundant — ios.yml builds on cache miss)
- Switch from actions/cache/restore to actions/cache (auto-saves on miss)
- Drop restore-keys and -stable suffix (no longer needed without prebuild workflow)
- Remove UDID resolution step (test falls back to --platform ios)
- Use point-free shouldRetry for isTransientSimulatorLaunchFailure
