fix: correct rroundResults typo in RoundInfo.vue

[MuraariK13052008]

What this fixes

The "Cancelled Tasks" stat in the Round Info panel always rendered blank for every round.

Root cause

Line 70 of RoundInfo.vue references rroundResults?.counts.total_cancelled_tasks but the declared ref in this component is roundResults (single r). JavaScript resolves undefined?.anything silently to undefined rather than throwing an error, so the bug never surfaced as a console error — it just always showed blank.

Fix

Renamed rroundResults → roundResults on line 70.

Files changed

• frontend/src/components/Round/RoundInfo.vue

How to verify

1. Open any campaign round that has at least one cancelled task
2. Navigate to the Round Info panel
3. Confirm the "Cancelled Tasks" field now shows the correct number instead of blank
