[UI] Some chunks are larger than 500 kB after minification

[serene-kitfisto-8899]

Hi,

When building the Cosmian KMS WebUI for production, Vite ( https://vite.dev ) emit the fallowing message :

 (!) Some chunks are larger than 500 kB after minification. Consider:
 - Using dynamic import() to code-split the application
 - Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/configuration-options/#output-manualchunks
 - Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.

The WASM client is, to be honest, pretty big. : (5Mo aka 3 x the size of DOOM ;-) )

dist/index.html                                             0.52 kB │ gzip:   0.34 kB
dist/assets/cropped-favicon-cosmian-32x32-BVkavOsn.png      0.85 kB
dist/assets/cosmian_kms_client_wasm_bg-CXJuKM1p.wasm    5,148.79 kB │ gzip: 637.20 kB
dist/assets/index-Di2BxnRX.css                             14.70 kB │ gzip:   3.76 kB

Maybe we should try some optimizations using binaryen / wasm-opt :

$ wasm-opt --enable-bulk-memory --all-features -Oz dist/assets/cosmian_kms_client_wasm_bg-CXJuKM1p.wasm -o dist/assets/cosmian_kms_client_wasm_bg-CXJuKM1p_opt.wasm
$ ls -sh dist/assets/cosmian_kms_client_wasm_bg-CXJuKM1p_opt.wasm
3.3M dist/assets/cosmian_kms_client_wasm_bg-CXJuKM1p.wasm

Please take a look at binaryen documentation : https://github.com/WebAssembly/binaryen/wiki/Optimizer-Cookbook
