[Haik]: refactor: co-locate UI primitives with AgentChat feature — delete avatar, button, collapsible, dialog, separator, and tooltip from src/components/ui, recreate them under AgentChat/_shared and component-local dirs (tooltip, avatar, dialog, separator), and rewire 13 consumer imports across OpenSwarmThread, ToolFallback, approvalToolkit, and nativeToolkit adapters
