Fix build errors: add missing mpl imports, fix indentation, update deprecated JAX API, fix undefined variable

- Add 'import matplotlib as mpl' to 7 files that use mpl.font_manager
- Fix docstring indentation in ogm.py (7 spaces -> 8 spaces)
- Update deprecated jax.lib.xla_bridge to jax.extend.backend in back_prop.md
- Fix undefined variable '失败者列表' -> 'loser_list' in house_auction.md
