feat(cdp): Persist to state instead of url

[benjackwhite]

Problem

The state of the configured hog function was put in the url for new functions but this had a few issues:

1. Redirecting to an integration slack loses the url so the state is gone
2. It only worked for new functions
3. It made doing beforeUnload logic super hard

Changes

• Moves to using a separate persisted reducer for the state with a timeout to ensure we don't keep it around way too long
• Adds the beforeUnload logic

👉 Stay up-to-date with PostHog coding conventions for a smoother review.

Does this work well for both Cloud and self-hosted?

How did you test this code?
