chore(demo-smart): update app ids

[florian-sanders-cc]

What does this PR do?

• changes the app-node & app-play app ids within the demo-smart file because previous demo apps have been deleted,
• adds grafanaBaseLink & consoleBaseLink to the context so they can be used to review the cc-tile-metrics component.

How to review?

• Check the commit,
• Run the storybook locally and check the demo-smart > tile-metrics page. With app-node, metrics should show up after a minute or so. With app-play, the component should show a message saying the app is stopped,
• One review should be enough for this one.

Note: this PR does not modify the cpu-load-bench app because I don't know if we still want to use it or not (it may be overkill now that the component is stable and we may not want to keep this app running constantly for nothing, I'll discuss it with Mathieu later on).
