feat: Gate exports by data pipelines feature availability

[tiina303]

Problem

For ability to unsubscribe from data exports we'll need to limit the old UI access
https://posthog.slack.com/archives/C0374DA782U/p1702644859275309

IMPORTANT: the available feature needs to be set-up first on billing to not block everyone's access.

Note: that the apps table now can have small empty rows for apps we're hiding, but it's the old UI ... so don't want to spend too much time making it pretty.

I didn't test this locally, I assume you did. I think this is fine for now, but for the new UI I think we should definitely show some sort of feature gate (eg "upgrade now to get access to this app") instead of showing nothing at all.

Oh and this should def wait to be merged until everyone is on the correct plans. I will manage merging this.

If they aren't subscribed they will still see the Batch Exports tab, but they'll get a paygate:
