fix: Resolve TypeScript build errors for verbatimModuleSyntax compatibility

- Fix EventEmitter import in page-contracts/store.ts (use default import)
- Add type declarations for eventemitter3 to fix ESM import type issue
- Add type declarations for react-copy-to-clipboard to fix React types mismatch
