fix(ci): use reactivecircus/android-emulator-runner for reliable boot

- Switch from manual emulator management to the proven emulator-runner action
- Use API 30 (boots faster than 34 with software rendering)
- Build APK before starting emulator to minimize emulator uptime
- All emulator-dependent steps run inside the action's script block
- Move env vars to job level for cleaner structure
