Improve error handling by replacing console.error/FIXME with Quasar notifications

[WillyEverGreen]

Problem

Currently, several components handle errors by logging them to the console with console.error and //FIXME or //TODO comments indicating that a proper alert is needed. This results in a poor user experience, as users are not informed when an operation fails.

Goal

Improve user-facing error handling by replacing these console logs with UI notifications using the Quasar Framework's Notify plugin, consistent with existing patterns in the codebase.

Affected files

The following files contain console.error calls marked with //FIXME or //TODO comments:

• MetisSelection.vue
• MetisWidget.vue
• DelayAndForwardingChart.vue
• DelayChart.vue
• DiscoChart.vue
• PrefixHegemonyChart.vue
• NetworkDelayChart.vue
• NetworkDelayAlarmsChart.vue
• CountryHegemonyChart.vue
• Latencymon.vue

Proposed solution

• Import useQuasar from quasar
• Initialize it in the component:

  const $q = useQuasar();

Hi! Happy to work on this and submit a PR if the approach makes sense.

We are currently having in-house discussions about the next steps for the website, specifically focusing on UI improvements. That said, I believe it’s best for the community to avoid implementing new features for now, as they may need to be reverted once we determine the next steps.

Understood, thanks for the clarification. I’ll wait for further updates before proceeding.
