fix: add wire:ignore to network traffic container and Chart.js retry logic

Root cause: wire:poll.2s on layout div caused Livewire to morph/overwrite
the JavaScript-rendered network traffic interface cards every 2 seconds,
replacing them with the server-rendered placeholder HTML.

- Add wire:ignore to #network-traffic-container to prevent Livewire DOM
  morphing from destroying dynamically rendered content
- Add retry logic (10x at 300ms) to createChart() for when Chart.js CDN
  hasn't finished loading (e.g. during wire:navigate)
