refactor: Move seek logic into _open_and_parse_file_with_openpyxl

Address reviewer feedback from @darynaishchenko (Comment 2555661755):
- Move fp.seek(0) try/except block into _open_and_parse_file_with_openpyxl
- Add info-level logging for seek failures instead of silent pass
- Remove duplicate seek logic from open_and_parse_file orchestration method
- Add hasattr check to avoid AttributeError on non-file-like objects
- Simplify orchestration method to focus purely on flow control

This centralizes fallback-specific concerns within the openpyxl path and
makes the behavior easier to test and reason about.

All local checks pass:
- Unit tests pass (4 passed, 1 skipped)
- MyPy type checking passes
- Ruff format and lint pass
