Remove EventAction import to resolve dev-server compilation error

[aaronkanzer]

EventAction is an unused import -- in which type-checking fails when running npm run dev-server locally -- simple PR to remove import until it is either used or intentionally removed

This issue persisted when trying on node >= 22 (verified locally via nvm use 22 and nvm use 23)

Indeed, it seems that I missed something regarding the type inclusion. It's weird the linter didn't catch it on the PR. This line can be removed for sure.
