cluster-ui: derive app name from route parameter in cluster-ui

Fixes: #70998

Release justification: category 2

Previously, we were deriving the selected app name from the
query string parameter in for the statements page in the
cluster-ui package. The selected app name should be derived from
the route parameter for the statements page.

Release note (bug fix): the selected app name in the statements page
is now derived from the route parameters.
