fix: revert relative base path and fix processor table overflow

Revert base: './' back to '/' — relative asset paths break on deep
URLs like /dashboard/app/route where the browser resolves assets to
/dashboard/app/assets/ instead of /assets/.

Also fix processor metrics table clipping: remove flex:1/min-height:0
from .processorSection so the table takes its natural content height
and the page scrolls to show all rows (was clipping at ~12 of 18).
