Fix 6 critical bugs in REPPO repository preventing execution

- Fix missing MUON optimizer by replacing with optax.adam
- Fix Hydra configuration parameter paths (env.name instead of env_name)
- Fix BraxGymnaxWrapper method signatures to accept params argument
- Fix training loop division by zero with proper total_time_steps
- Fix incorrect algorithm name in wandb (reppo instead of sac)
- Fix JAX key batching error in BraxGymnaxWrapper reset method
- Add comprehensive HoReKa SLURM integration with wandb logging
- Update README with detailed bug documentation and fixes
