feat: Search Events (#25)

* first pass at a search function refs #24

* logic to make it works is important 😅

* missed a spot

* it works!!!!@!@!@!@

just a few details to clean up

* ok no it works the way we want!

- updates list in real time as you type in search
- arrow back lets you keep search
- x button in search bar clears search
- physical back button clears search
