fix(ci): windows clippy + rustfmt debt from the D3D11VA push

The windows workflow has been red since a69a83b5: clippy 1.96 rejects the two
field-reassign-with-default view-desc initializers in video_d3d11.rs (now struct
literals), and with clippy failing first, the rustfmt step never ran — cargo fmt
--all had genuine misses queued up in video_d3d11.rs / pf-presenter d3d11.rs +
vk.rs / core abr.rs + client.rs (plus this session's config.rs). Formatting only
beyond the two initializers; no behaviour change.

Verified: clippy -p pf-client-core --all-targets -D warnings clean on the RTX
Windows box, cargo fmt --all --check clean, core lib tests green.
