test(e2e): register API-key client flow + fix nav-rename selectors

Adds TC-CL-003 (WDIO): open Apps, register a client, generate, and assert the
mcpk_ key is shown once. Fixes specs the Workspaces→Mapping nav rename broke:
clients.wdio now asserts "Mapping"; navigation + user-flows click the "Mapping"
nav directly (their old has-text("Spaces").last() had incidentally matched the
"Workspaces" button via substring).
