chore: pin Flutter 3.41.9 lewat FVM

Stack codegen project ini (freezed 2.x, build_runner 2.5, analyzer 7.7.1) hanya paham bahasa Dart sampai 3.9. Flutter 3.44+ membawa framework yang ditulis di bahasa 3.10+, dan analyzer 7.7.1 crash saat men-serialize-nya (visitDotShorthandPropertyAccess) sehingga build_runner tidak bisa jalan sama sekali.

3.41.9 adalah rilis terbaru yang framework-nya masih di bahasa 3.9. Versi dipin per-project lewat .fvmrc supaya tidak mengganggu project lain di mesin yang sama.

android/build/ ikut di-ignore; isinya artefak Gradle.
