Comments in benilla-assets and benilla-ui: three reference facts corrected, one deviation labelled (#290)

Comment corrections in crates whose comment pass has already landed. Comment text only: every file strips to identical code.

- Fixes #61. The `<Script file=>` note in `benilla-ui`'s loader now names the install directory as the reference's scan root (`0x646ea0`, from Storm's base path `0xc52418`), not the process's working directory. The deviation it records is unchanged.
- Fixes #96. `liquid.wgsl` no longer labels the ADT water alpha a deviation. The swatch's own alpha is what the reference uses: the `0xc7fbc0` table's texture binds only behind `[0xc800ec]`, which never holds one.
- Fixes #117. `wmo.rs` now gives prop creation as the streaming-window commit (`0x698720` → `0x695aa0`, once per group) and per-frame visibility as the portal walk's admission (`0x685d70` → `0x6838f0`).
- `model.rs`: the billboard-card normal flip carries the Deviation label, with the reason `benilla-formats` already gives where the test lives: the reference shades such a card inverted and camera-dependent.
