dual-gpu fix & nvme

- Replaced the restrictive head -n1 hardware parsing with a dynamic while read loop. The script now fully detects and registers multiple coexisting GPUs (Intel+Nvidia / AMD+Nvidia).
- Rewrote install_gpu_drivers() in modules/gpu.sh from a mutually exclusive case block to independent, sequential if conditions. Laptops now install both integrated firmware (Intel/AMD with non-free VA-API acceleration) and dedicated graphics stacks (Nvidia driver + 32-bit libs for Steam) seamlessly in a single pass.
- Improved Nvidia Kepler architecture guards under Debian 13 (Trixie). The script now safely skips missing legacy Nvidia packages without aborting or crashing the remaining Intel/AMD configurations.
- Added nvme-cli utility installation across all Debian versions. For Bookworm and Trixie, it features dynamic hardware validation via lsblk transport filtering and interactive, real-time SMART log viewing with an execution screen-pause.
- Created a brand new standalone module (modules/extras/dev/jellyfin.sh) to cleanly inject Jellyfin Media Server across Debian 11, 12, and 13 using its official setup script, protected by strict SHA256 checksum validations and guaranteed error-cleanup.
- Added OpenRGB to the Gaming menu for Debian 12 and 13. Implemented secure curl downloads with an emulated Chrome User-Agent to bypass Codeberg bot blocks, complete with automatic i2c-dev module configuration, user groups provisioning, and udev permission rules execution.
- Standardized menu headers across 15 separate files using a centralized readonly SCROLL_HINT=" [↑↓]" variable, replacing messy hardcoded strings with clean, uniform Whiptail instructions.
