Fix some CI (windows + nasm, core-macro error) (#2676)

* Moves index.html creation until after wasm creation so the webserver doesn't prematurely serve the page
* sets up nasm for windows builds (to be superseded by Remove Dioxus CLI NASM dependency #2666 #2682)
* puts magnanis-cli-support in a blocking task to prevent threadlocking during sequential builds
* changes order of client/server builds such that the client is built before the server so the webserver doesn't prematurely serve invalid client code
* declobbers "serve" such that each project gets a different dir in the target folder
* uses nest_service instead of fallback so the router doesn't respond with fallback codes
* reincorporates doge's fix from Fix hot-reloading on Windows #2544
