fix(frontend): bump lucide-react to ^1.8.0 and align with Cloud UI

Cloud UI recently upgraded lucide-react to ^1.8.0. Because both apps
declare lucide-react as a `singleton` in their Module Federation config,
the Cloud UI host provides a single instance for the Console remote to
consume. With Console pinned at ^0.563.0, the constraints are disjoint
and MF resolves to Cloud UI's 1.8.0 — where `Linkedin` no longer exists
(removed upstream for trademark reasons) — so Console's footer rendered
`undefined` and the entire Console MF mount errored on every cluster
route in Cloud UI.

Align Console with Cloud UI and drop the now-unexported LinkedIn icon:
- package.json: lucide-react ^0.563.0 -> ^1.8.0
- components/icons/index.tsx: remove the `Linkedin as LinkedInIcon` re-export
- components/layout/footer.tsx: drop the LinkedIn link and its import
