fix(apps): reword copy that trips the role-hijack scanner

`prompt_injection_role_hijack` is critical/block and its `you are now …`
pattern matches ordinary product copy, so the Flask fixture's
`flash('Congratulations, you are now a registered user!')` fired on every read
of its auth routes — 30 critical matches in one orchestrator run. Triage
overruled all of them, but a critical match is terminal, and warlock fails
closed when a triage call errors: one gateway blip on this fixture kills the run.

Rewords the four tracked strings without changing meaning, keeping the gettext
msgid identical to the source and the spec assertion in step with the copy it
asserts.

The remaining hits are wizard run leftovers under `.claude/skills/**/EXAMPLE.md`
(untracked; their text comes from context-mill's example-apps) and the untracked
`apps/audit/posthog-demo-3000/app.py`.
