[Reviewer] Dashboard Review: Interface-Bereinigung, SVG-Composable-Extraktion, Komponenten-Renaming, CSS-Fix

- AgentNodeData: Remove redundant fields task/runtime (dup of currentTask/runtimeSeconds)
- useTeamNetworkSvg: Extract SVG layout, path computation + pulse animation from TeamNetwork
- TeamNetwork: Use AgentNodeData type, fix undefined pulseElements2/storePulseRef2, remove unused props
- Rename MissionCard.vue → TaskCard.vue (matches actual usage)
- Extract FeedDetailModal from OperationsFeed (eliminates :global() CSS conflict with AgentModal)
- DashboardView: Fix type import path (../../ → ../), remove dead TeamNetwork props
- AgentModal: Remove unused thinkingStreamRef template ref
