fix: move skill source badge beside install button in hub cards (#502)

The hub card UI is rendered by the local private HubSkillCard in SkillsScreen.kt (not the unused components/HubSkillsTab.kt copy). Moved SourceBadge out of the top-right name row to the left of the Install button in the card footer (left-aligned source, right-aligned action), tying the skill origin (hub/clawhub/etc) to the install action.
