Issue: Misunderstanding of Seed Phrase Restoration Scope

[jpl-btc]

Some users believe the seed phrase will restore the entire Alby Hub status, including channel states. This misunderstanding has been observed among new users several times.

To prevent this, add a warning pop-up before the page where the seed phrase is copied. The pop-up should briefly explain what the seed can restore, what it cannot, and how users can recover channel funds in case of device or hub failure.

We improved the copy a bit on this backup page, but I think we still need to link to the new guide that @reneaaron and @jpl-btc are working on.

Edit: we should probably also include it on the advanced setup -> restore from seed page
