feat(paddle): Enable ANN rule for 16 additional files across multiple directories

- Enable ANN rule for 16 new files, expanding from 9 to 25 total files:
  - All __init__.py files across entrypoints, train, infer, model subdirectories
  - Model infrastructure: task.py, base_fitting.py, base_descriptor.py
  - Utility modules: dataset.py (with class method annotations), decomp.py, env.py, auto_batch_size.py
  - Inference: inference.py with complete Tester class type hints
  - Root: __init__.py
- Added comprehensive type annotations to Dataset class methods (__len__, __getitem__, add_data_requirement)
- Fixed enable_prim function return type annotation in env.py
- Added type hints to Tester class constructor in inference.py
- Progress: 25 files now have ANN rule fully enabled (2,400% increase from initial 1 file)
