fix(ci): use ubuntu-latest runner label and Flutter 3.35.3 (correct version)

- Runner label: self-hosted -> ubuntu-latest (act registers as ubuntu-latest, not self-hosted)
- Flutter SDK: 3.44.8 (nonexistent) -> 3.35.3 (latest stable)
- SDK platform: macOS -> Linux (act runs Linux containers)
- JDK: macOS ARM64 -> Linux x86_64
- Android cmdline tools: macOS -> Linux
- iOS build: skip gracefully (requires macOS host with Xcode)
