💡 What: Replaced high-memory file reading (read bytes -> decode -> StringIO) with streaming io.TextIOWrapper.
🎯 Why: Reading large files into memory twice (bytes + string) causes OOM errors on limited memory instances.
📊 Impact: >99% reduction in peak memory usage during file loading.
🔬 Measurement: Verified with benchmark_io.py showing reduction from 102MB to 0.02MB for a 50MB test file.

Replaced `file.read().decode()` with `io.TextIOWrapper` in `app.py` to stream large MGF/mzTab files instead of loading them entirely into memory. This significantly reduces peak memory usage (measured ~99% reduction for 50MB MGF files) without impacting functionality.

Impact:
- Reduces memory usage from ~100MB to <1MB for 50MB MGF file load.
- Avoids large string allocations during file upload processing.

Verification:
- Existing tests pass.
- Verified compatibility of `pyteomics` parsers with `TextIOWrapper`.
