fix: Fix session search behavior (#1357)

# Summary

This PR fixes a few bugs in the session search page:

1. Clicking ENTER now triggers a form submission on the session page for lucene conditions (SQL conditions already worked)
2. Clicking ENTER now triggers a form submission on the session side panel for both lucene and SQL conditions
3. The WHERE condition in the search sidebar is now interpreted in the correct `whereLanguage` instead of assuming lucene. Partially reverts #863, but I confirmed that the page-level search does not filter the sidepanel spans after this change.

This PR also fixes the same issue (ENTER now submits forms) on the dashboard and services page. #1208 introduced the issue by preventing the ENTER event from bubbling up to the form when using `AutocompleteInput` / `SearchInputV2`.

Closes HDX-2816
