Subject: fix(ui): use portable crypto API and async bootstrap pattern
X-Git-Tag: cli@v4.5.0~37
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=3c6f6f11211b476fe050cd54d5bb6829c7bdbfc1;p=e-mobility-charging-stations-simulator.git

fix(ui): use portable crypto API and async bootstrap pattern

- Replace node:crypto import with globalThis.crypto.randomUUID() in
  ui-common UUID utility for browser compatibility
- Rewrite ui-web main.ts with async bootstrap() pattern instead of
  top-level await, following Vue.js community best practices
- Remove unused ToastPlugin registration (all code uses useToast()
  composable directly)
- Add granular error handling for fetch, parse, and init phases
