Describe the bug

Trying to filter dashboard's card results using "text/contains" filter can be confusing since it's case-sensitive.

To Reproduce

1. Save sample database's People table as a GUI question
2. Add the question to a dashboard
3. Create a "text/contains" dashboard filter and connected it to "People — Name"
4. Save changes
5. Try to search for "Hudson" and for "hudson"
6. "Hudson" has results and querying "hudson" has no results

Expected behavior

"text/contains" should be case insensitive or there should be a way to manage to control the behavior.
