cleanup: remove now-unused stripe pricing table remnants (#7557)

Removes vestigial remnants of the Stripe pricing table integration,
which was replaced in
https://github.com/Comfy-Org/ComfyUI_frontend/pull/7359. The feature
flag is now obsolete, but was forgotten about in that PR. This PR cleans
everything up fully.
