Fix icon names to use available icon files

Changed icon names to match available icons in layouts/partials/icons/:
- ai → bot (infrastructure-engineers)
- unlock → global (multicloud)
- key → lock (multicloud)
- dashboard → monitor (platform-teams)
- check → security (platform-teams)
- growth → rocketship (platform-teams)
