fix(core): ensure compatibility with Python < 3.12 for Buffer import

Use try/except to import Buffer from collections.abc, falling back to bytes
for older Python versions where Buffer is unavailable. This improves
backwards compatibility of ohlcv_file.py.

fix(tests): ensure import hook is registered before pynecore imports

Register the import hook at the top of conftest.py to guarantee AST
transformations work, even if __pycache__ is deleted. This change
prevents issues with module imports during test execution.

fix(strategy): use prefixed order IDs to avoid entry/exit collisions

- Add "entry_" and "exit_" prefixes to order IDs in position.orders to
  prevent collisions between entry and exit orders.
- Update all logic for adding, removing, and accessing orders to use
  the new prefixed keys.
- Adjust commission handling and order deletion to account for prefixed
  IDs.
