Feat/90 calendar zoom

[nmhossain02]

Addresses #90

This PR is a draft of different options available to allow zooming on the calendar screen. Being a very open-ended ticket, I decided to show three different options for how to vertically zoom on the retreat view:

• Button toggle
• Slider
• Ctrl+Scroll

Throughout my work, I had to touch the Sidebar component, extract some code into a separate CalendarContent component, and use CSS grid to lay out the retreat view in a more controllable way. I also created a CSS class to hide scrollbars.

This isn't quite mergeable, but I hope this work allows us to refine our exact requirements for this feature.
