Remove Active Sites card from sidebar

The card showed hardcoded '5 projects · 3 flagged · 2 on schedule'
stats that were never updated from the mock data and duplicated
information in the Sites module. Removing it gives the sidebar a
cleaner Logo → Nav → Lock structure and means the Lock screen button
is visible without scrolling on standard heights.

Also align the mobile drawer's close-button breakpoint from lg to xl
to match the rest of the sidebar's breakpoint logic.
