Fixes and Tweaks:
- Fixed filters in operations. Filters are combined using AND, except when consecutive filters refer to the same column, and the operations are Equals, Contains, or In. Such filters are parenthesized and combined using OR within the parenthesis.
- Fixed "Delete duplicates" operation that failed to delete records if some values were NULL.
- Fixed "Join" operation that failed when the table name had special characters (e.g. "-").
- Fixed "Number chart" that sometimes rendered too small.
- Added a notification to tell the user that a new version is deployed and they need to refresh the browser.
- Changed how scheduled tasks (e.g. ServiceNow import) are saved at the backend.
