test(8.10): narrow cprst persistence feature to Web Modeler only

The cprst scenario blocked the merge queue because the persistence feature
file also enabled Optimize persistence (SUPPORT-30042) and orchestration
extraVolumeClaimTemplates (SUPPORT-30094) — known-broken paths that this PR
does not fix. The Optimize migration init container hangs on PodInitializing,
failing cprst for reasons unrelated to the Web Modeler restapi /tmp fix.

Narrow the feature to webModeler.persistence only so cprst exercises the path
this PR actually changes. Optimize and orchestration coverage will be
re-enabled in the corresponding template-fix PRs.
