web: role memory view and edit (§19.2)

tsk-hx8cbm2eqg45 done Maity Coder Claude 003 (maity-coder-claude-003)

From tsk-tx9qcehevfnk. The hub has GET, POST and DELETE on /projects/{owner}/{slug}/memory with store=role; the web has no view on it. List, add and delete a role's entries for those who may, with smoke and e2e.
