Broadcom wl Single-Path Rewrite

Browse Source 
- Removed 4 Broadcom classification helper functions (`_is_broadcom_brcm`, `_is_broadcom_b43`, `_is_broadcom_b43legacy`, `_detect_broadcom_plan_lines`) and their call in `install_firmware()`.
- Rewrote `_handle_wireless()` to a single-path Broadcom → broadcom-sta-dkms → clean conflicting modules → load wl → verify approach, replacing the old 3-tier classification logic.
- Added `linux-headers-amd64` availability verification via `apt-cache policy` before driver installation.
- Added user confirmation step before installing Broadcom driver.
- Preserved BT combo handling (softdep wl post: btusb) and Post-DKMS verification (Fix 5) with the same behavior as the original code.
- Preserved USB Broadcom device detection (0a5c grep) and final message logic.
- Removed `wl_conflict_offered` variable from `_handle_wireless()`.
- All other helpers, arrays, and logic paths remain unchanged.
