Enable application insights for Frontend

[arealmaas]

We need to ensure that unhandled exceptions and other caught exceptions are logged and visible in application insights

Possible steps in this task:

Instrument the client with Application Insights

• Install Application Insights for automatic collection of telemetry. Can take inspiration from the studio-team: https://github.com/Altinn/altinn-studio/blob/main/frontend/packages/shared/src/contexts/LoggerContext.tsx

Extend with using the react javascript framework

• Capture unhandled exceptions
  • Add the React error boundary component and more

Extend with custom metrics for better analytics (component usage, track user events etc)

• Await here until discussion in Digdir about which tool to use is resolved: https://digdir.slack.com/archives/C079D6P85AQ/p1724928306671149?thread_ts=1724676605.239799&cid=C079D6P85AQ
