feat(mgmt/web): surface the host.env encoder pin so a conflicting GPU choice isn't invisible

Browse Source 
listGpus gains encoder_pin (PUNKTFUNK_ENCODER when it actually pins something —
unset/auto stay null), and the console's GPU card shows it: a muted note when
the pin is compatible, an amber warning naming the pinned vendor and the next
session's GPU when it contradicts the selection (the host overrides such a pin
at session open — without this field the selection just looked broken). Docs
updated to say the adapter wins.

| `PUNKTFUNK_VIDEO_SOURCE` | `virtual` · `portal` | `virtual` creates a per-client display at the client's exact mode (the normal choice). `portal` captures an existing monitor instead. |
| `PUNKTFUNK_ZEROCOPY` | `1` · `0` *(default on)* | GPU zero-copy capture→encode (dmabuf → CUDA → NVENC, or D3D11 on Windows). **On by default** — no need to set it; it falls back to a CPU path automatically. Set `0` to force the CPU path. One exception: Windows **Intel/QSV** keeps the CPU path by default until zero-copy is validated on Intel hardware — set `1` to try it there. |
| `PUNKTFUNK_INPUT_BACKEND` | `libei` · `gamescope` · `wlr` · `uinput` | How input is injected. `libei` for GNOME/KDE, `gamescope` for Bazzite/gamescope, `wlr` for Sway/wlroots **and Hyprland**. Auto-detected with the compositor. |
| `PUNKTFUNK_ENCODER` | `auto` · `nvenc` · `vaapi` (Linux) · `amf` · `qsv` (Windows) · `software` | Encoder backend. `auto` (default) detects the GPU vendor: NVIDIA→NVENC, AMD→VAAPI/AMF, Intel→VAAPI/QSV. `software` (aliases `sw`/`openh264`) is the GPU-less H.264 path on both platforms — on Windows `auto` falls back to it when no GPU is found; on Linux it is **explicit-only** (`auto` never picks it). |

On a multi-GPU Windows box a forced hardware backend whose vendor contradicts the selected GPU (web-console preference) is **overridden** — the adapter wins and the host logs a warning; remove the stale pin. |
