Search improvements

[LucasPickering]

Description

Describe the change. If there is an associated issue, please include the issue link (e.g. "Closes #xxx"). For UI changes, please also include screenshots.

Replace recipe search with a filter, meaning items that don't match aren't shown. This should hopefully make it easier to find what you're looking for in a large list.

Also, propagate events not consumed by the text box to the recipe list, so you can scroll up and down while still in the text box.

Known Risks

What issues could potentially go wrong with this change? Is it a breaking change? What have you done to mitigate any potential risks?

This may still not be the right UX, but I can always change it again later.

QA

How did you test this?

Manually, updated a unit test too
