Description & motivation 💭

• move Activity Details route from src/routes/(app)/namespaces/[namespace]/activities/[activityId] to src/routes/(app)/namespaces/[namespace]/activities/[activityId]/[runId] and adjust links from List and Create pages.
• Add a minimumVersionRequired check for server version 1.30.0 for nav link and guard.
• make sure route ID is passed in initial call to DescribeActivityExecution
