Display filtering controls inline for FILTERING round type

For rounds with roundType=FILTERING, the filtering controls (run button,
stats, finalize) are now shown directly on the round detail page instead
of requiring navigation to a separate /filtering page. Rules configuration
and results review still link to their dedicated pages for detailed work.
