fix(frontend): resolve JSX parse errors introduced by merged PRs

- Remove extra closing </div> in ChatHistorySidebar that placed
  the delete-confirm modal outside the return tree (PR #429)
- Add missing imports for SplitViewComparison, ChatSearchPanel,
  useChatHistory, and useSplitView in StellarChatInterface

npm run build now passes cleanly (16/16 static pages generated)
