* [web] Redirect missing AI add-on purchase to subscription dashboard
The two error paths in `previewAddonPurchase` redirected to
`/user/subscription/plans#ai-assist`, but the `#ai-assist` anchor was
removed when the AI Assist add-on was retired, so users land at the top
of the plans page with no context. Align both with the other error
branches in the same function and the `plans-2026-phase-1` enabled
branch, which already redirect to
`/user/subscription?redirect-reason=ai-assist-unavailable` — the
subscription dashboard shows the matching warning alert
(`redirect-alerts.tsx`).
Update the acceptance test to match the new redirect target.
Closes#34074

* [web] Update ai-assist-unavailable warning to reflect bundled AI features
The previous copy said "AI Assist isn't available to you due to your
current subscription type", which read as a hard block. Now that the AI
Assist add-on has been retired and AI features are included with every
paid plan, the warning should point users to the pricing page instead of
implying their plan can't access AI at all.
Keep the existing translation key for now — a follow-up can rename it
once #33624 (AI page CTA destination) is resolved.
