nvidia driver stability & version menu

- Refactored NVIDIA installation with robust DKMS verification (`_verify_nvidia_dkms_build`). Automatically detects build failures for the current kernel and repairs them via `dpkg-reconfigure`, ensuring modules compile against active kernels without manual intervention.
- Added Secure Boot detection (`_nvidia_secure_boot_enabled`) to warn users if the NVIDIA module is compiled but unsigned, preventing boot issues on systems with UEFI security enabled.
- Implemented `_configure_nvidia_wayland()` for Wayland support. Detects hybrid laptops (Optimus) vs desktops using DMI chassis types and battery presence. Configures `NVreg_PreserveVideoMemoryAllocations` only for desktops to avoid Optimus conflicts, and adds architecture-specific guards (e.g., Kepler warnings).
- Introduced version selection menu (`_show_nvidia_version_menu`). Users can select driver versions (470/535/550/590/595) based on Debian release. Parametrized CUDA repo installation for 590/595 with post-install DKMS branch verification.
- Fixed state inconsistency bugs in `NVIDIA_DRIVER_MODE`. Added guards to ensure configuration files are only written upon successful installation, preventing partial setups after failures (e.g., backports, CUDA repo).
- Improved hardware detection helpers (`_is_hybrid_laptop`, `_get_nvidia_arch_family`). Prevents false positives on multi-GPU desktops by verifying iGPU presence alongside dGPU.
- Updated Java/Minecraft support in `modules/extras/java.sh`. Added Temurin 25 ("Minecraft 26+") to the runtime selection menu and updated documentation.
- Enhanced utility robustness (`_run_cmd`, `_configure_lightdm`). Properly propagates exit codes from commands and handles failures gracefully (yellow warnings + skip) instead of crashing under `set -e`.
