dual-gpu & audio fixes + flatpak migration

- Fixed `set -euo pipefail` crashes across hardware detection: Added `|| true` guards to all `nvidia-smi`, `dpkg -l`, `apt-cache policy`, and `nvidia-detect` pipelines in `sysinfo.sh` (3 lines) and `gpu/nvidia.sh` (7+ lines).
- Created new Audio & Sound module (`modules/extras/audio/audio.sh`) with Debian version-specific logic: Bullseye basic mode vs Bookworm/Trixie standard PipeWire stack, plus ALSA utilities, pavucontrol, pulsemixer, playerctl. Added menu entry "14 Audio & Sound".
- Migrated Flatpak from System Tools to Software Center category. Renamed menu to "Software Center & Flatpak", converted single-select to multi-select checklist in `software_centers.sh`, removed logic from `system.sh`.
- Implemented robust time synchronization: New `_ensure_time_synced()` function in `utils.sh` forces NTP active, validates timezone with interactive `dpkg-reconfigure tzdata` if needed, restarts `systemd-timesyncd`, and verifies sync status. Replaced `check_system_time` call in main script.
- Fixed System Info network detection: Removed hardcoded 2-line height limit (now dynamic via terminal size), fixed hard-coded array indices to use progressive counters for multiple interfaces including USB WiFi adapters.
