feat(gui1d, physics): implement interactive 1D simulator GUI & fix avalanche generation sign bug

Browse Source 
- gui1d:
  - Created interactive 1D Diode simulator dashboard (gui1d/app.py, solve_1d.py).
  - Redesigned doping process step editor, layout, and centered legend plots.
  - Implemented state caching for I-V sweeps and grid spacing optimization.
  - Doubled voltage step resolution: 0.05V step for V < 1V, and V/20 step for V >= 1V.
- physics (avalanche bug fix):
  - Fixed charge sign in Hole Continuity Equation for avalanche generation.
  - Created AvalancheGeneration_p in physics/new_physics.py to correctly act as a hole source.
  - Resolved physical breakdown current polarity and negative current leakage at high reverse bias.
