WiFi Detection, vainfo & Java JRE

- Implemented multi-layered WiFi detection logic in `utils.sh`. Added PCI class text grep, exact `lspci -d ::0280` matching for wireless devices, Broadcom vendor ID fallback (`14e4`), and USB discovery via `lsusb`. Improved `sysinfo.sh` fallback message to guide users toward the Firmware option.
- Added `_pause()` execution after `vainfo` outputs in `gpu/_helpers.sh` (`offer_generic_tools`) and `gpu/amd_intel.sh` (`offer_amd_tools`, `offer_intel_tools`). Ensures users can review hardware info before proceeding with tool installation.
- Refactored Java selection in `extras/java.sh`. Switched from single-option `--menu` to multi-select `--checklist`, enabling simultaneous Temurin JRE installations with all versions enabled by default and iterative installation logic.
