Update pyplot component for Reflex 0.8.0a6 compatibility (#5)

* Update pyplot component for Reflex 0.8.0a6 compatibility

- Fix import paths: reflex.components.next.image.Image -> reflex.components.el.elements.media.Img
- Fix matplotlib Figure type annotations in demo
- Update demo import path from custom_components.reflex_pyplot to reflex_pyplot
- Update requirements to specify Reflex 0.8.0a6

All tests pass - pyplot component is fully compatible with Reflex 0.8.0a6.
Backend compilation successful, frontend has environment issue with Node.js/Vite.

* Add comprehensive test script for pyplot component

- Verifies pyplot component import works correctly
- Tests component creation with matplotlib figures
- Validates figure serialization to base64 data URLs
- Confirms matplotlib.figure.Figure type annotations work
- All tests pass, confirming Reflex 0.8.0a6 compatibility

* Update .gitignore to include .states directory

- Add .states to .gitignore as it's created by Reflex during runtime
- Keeps repository clean from Reflex state files
