* feat(ui): New status page UI * docs: Rename labels to extra-labels * Fix domain expiration test * feat(ui): Add ui.default-sort-by and ui.default-filter-by * Change ui.header default value to Gatus * Re-use EndpointCard in Details.vue as well to avoid duplicate code * Fix flaky metrics test * Add subtle green color to "Gatus" * Remove duplicate title (tooltip is sufficient, no need for title on top of that) * Fix collapsed group user preferences * Update status page screenshots
