chore: dedup dead code + compress utility

- Hapus src/shared/utils/retry.ts (0 imports, dead)
- Hapus src/shared/errors/index.ts (7 classes, 0 imports)
- Hapus drizzle type exports dari schema.ts (tidak dipake)
- Hapus src/config/index.ts, redirect 8 imports langsung ke env.ts
- Ekstrak maybeCompressChunk ke shared/utils/compress.ts
- Hapus duplikasi gzipSync di upload-file.ts + chunked-storage.ts
- Lint clean, build clean
