dual-gpu fix & lspci cache

- Replaced the restrictive Broadcom firmware installation flow with a persistent, step-by-step process in modules/firmware.sh. Now installs dkms, wireless-tools, and linux-headers-amd64 separately, then applies blacklist configuration, updates initramfs, and loads conflicting modules properly.
- Fixed conky package name across system.sh and bullseye/extras.sh. Changed from "conky" to "conky-all" with corresponding state variable updates for correct installation via apt.
- Corrected broken GRUB sed command in modules/gpu.sh for AMD GCN support. Added grep guard to prevent duplicate parameter insertion and fixed regex pattern for proper cmdline modification.
- Added whiptail pre-flight check in debianito.sh. Auto-installs required TUI dependencies if missing before the main menu, preventing runtime failures.
- Fixed home directory path resolution bug in modules/sudo_config.sh. Replaced eval echo "~$USER" with getent passwd approach for reliable user home detection across SUDO_USER contexts.
- Implemented global lspci output caching across 18+ locations. Single cache population via _init_lspci_cache() before detect_gpu, all subsequent reads use LSPCI_OUTPUT variable to eliminate redundant hardware polling calls.
- Added apt update deduplication helper in modules/utils.sh. _ensure_apt_updated() with APT_UPDATED flag bypasses redundant package list refreshes across extras/, gaming/, firmware/, and desktop_display/ modules while preserving transactional rollback paths in repos.sh.
- Fixed STATE_REFRESHED logic in debianito.sh main_menu case statement. Added STATE_REFRESHED=true to branches 3, 5, 7, 9, 11, 12, and 13 that mutate system state, ensuring refresh_system_state() triggers correctly after configuration changes.
- Removed dead REPOS_CONFIGURED variable from debianito.sh and modules/repos.sh. Variable was written but never read, eliminated to clean up global namespace without affecting repository functionality.
