fix: Update lint:ci to check TypeScript files and add ESLint overrides

- Updated lint:ci command to include .ts and .tsx files (not just .js)
- Added ESLint overrides to allow require() in config/build/test files
- Added overrides for story files to allow empty functions in examples

This fixes the CircleCI lint check failure by properly linting TypeScript
files while allowing legitimate CommonJS usage in:
- Config files (*.config.ts)
- Build scripts (scripts/**)
- Test utilities (test-utils/**)
- Cypress plugins
- Storybook stories

Result: 0 errors, 6 warnings (all pre-existing and acceptable)
