Fix broken dashboard scrolling (v2.4.1)

.aurora-dashboard-frame never got the height-cap + internal-scroll
treatment #wpbody-content got in an earlier session (it bypasses
#wpbody-content entirely, using its own element) — only the
taskbar-present variant applied to it. Combined with html/body being
locked to overflow:hidden in that same earlier fix, dashboard content
below ~1500px became completely unreachable: no internal scroll, and
no document scroll left to fall back on. Mirrored the same
max-height/overflow-y/overflow-anchor treatment onto the dashboard
frame. Verified live — Server Health, Media Analytics, and the rest of
the dashboard scroll into view correctly now.
