Pre-filter dashboard page

[rebeccakarasiktw]

✨ What new feature do you want to see?

Pre-filter the dashboard page upon every loading of the page, so that performance on the dashboard doesn't lag as much.

🇺🇸 States this change applies to

• ALL
• Nebraska
• Illinois

🧶 Acceptance Criteria

Given I'm an admin user, when I log into the dashboard, it should filter to the first site in the filter dropdown alphabetically automatically. And the dashboard should only load that option.
Given I'm an admin user, when I see the filtered dashboard, I am able to update that filter and filter for additional sites, or remove the filter altogether.
Given I'm not an admin user, when I log into the dashboard, it should filter to the first site that I have access to in the dropdown.
Given I've changed the filter and filtered for a particular site, that filter should remain filtered as I navigate to Attendance, Edit Attendance, and back to Dashboard.
