README: drop false HDMI claim and stale panel-overlay section

Browse Source 
Bug report 5 called out hardware claims that are not true. The RK3326
boards have no HDMI or any video output, so remove "HDMI audio/video
output" from the feature list. Qualify Bluetooth (works via a USB
adapter, there is no internal radio). Rewrite the Display Panels section
and the overlays feature bullet: the 43 pre-generated overlays and the
config/archr-dts + mipi-generator tree they referenced were removed in
2.0 in favor of the online overlay generator, and report 3 shows users
still following the stale instructions.

### Display Panels
Arch R ships 43 pre-generated MIPI panel overlays covering all known R36S display variants, named after the exact motherboard revision (e.g. `R36S-V21_2024-12-18_2551.dtbo`, `G80CA-MB_V1.3-20251212_Panel_8.dtbo`). Panel selection is done by copying the correct `.dtbo` file to `overlays/mipi-panel.dtbo` on the boot partition. Sources live under `config/archr-dts/{original,clone,soysauce}/<MB-revision>/`; the build extracts the panel description from each revision's `rk3326-r36s-linux.dtb` via `config/mipi-generator/generator.sh`.
Panel overlays are not baked into the images. Generate the overlay for your exact motherboard revision at the online generator, https://arch-r.io/overlay-generator/ (pick your board, or upload the stock `dtb` from the SD card that shipped with the device), then copy the resulting file to `overlays/mipi-panel.dtbo` on the boot partition. The Arch R Flasher can also generate and install the overlay during flashing. The `/flash/overlays/` folder on a fresh install contains a `README.txt` with the same instructions.
