Restore eslint-disable directives needed for CI

The previous commit removed eslint-disable directives that appeared
unused locally, but these are actually required for CI which has
different ESLint rule configurations.

CI errors:
- @typescript-eslint/no-deprecated for unmountComponentAtNode
- @typescript-eslint/unbound-method for method assignments

These directives appear as "unused" warnings locally but prevent
real errors on CI, indicating environment-specific ESLint config.
