chore(web/wiki): Rename web/wiki-dioxus to web/wiki, retiring the React app
The Rust/Dioxus/WASM port is now the wiki: delete the former React/Deno app at
web/wiki and move the port into its place (web/wiki-dioxus -> web/wiki). Rewire
the flake: drop the ./web/wiki-dioxus import, rename the deployable frontend
package wiki-dioxus-frontend -> wiki-frontend and the dev shell wiki-dioxus ->
wiki (both freed up by deleting the old app), and fix the external references
(root README, typos exclude, homepage comment, in-dir README/PLAN/deslop/pwa).
The internal Dioxus/Cargo app name stays wiki-dioxus (so target/dx/wiki-dioxus is
unchanged) and the live Scaleway registry namespace rg.fr-par.scw.cloud/wiki-dioxus
is left intact. Moving the whole tree re-stages it under repo-wide hooks that never
scanned the port before; scope biome (a JS/TS linter; the port is Rust), lychee
(intentional example/SSRF URLs), deslop (the newer appview/ballot crates are a
separate, un-tuned backend workspace), and typos (technical false positives) to
skip web/wiki, and drop an unused lambda arg deadnix flagged. The app keeps its own
gates (rustfmt/clippy/cargo test/check-css-spacing). Verified: the flake evaluates
and the app compiles.
