Pre-fund invite links

[ekzyis]

Describe the problem you're trying to solve

Using CCs for payments and for invites at the same time is awkward. Keeping enough CCs in your wallet is hard because you will spend from the same balance to pay for SN fees so stackers need to manually make sure that their balance is always enough to honor redemptions.

This is especially bad for unlimited invites since you never know how many redemptions you might need to honor.

Describe the solution you'd like

Allow to fund invite links with CCs. This means these CCs are reserved to be used for redemptions. If an invite link is revoked, the CCs will return to the inviter.

For unlimited invites, it might make sense to also allow withdrawing from an invite link without revoking it.

Maybe funding invite links should also be mandatory and not optional since it should improve UX for inviter and invitee a lot. Making it optional might sound like there are drawbacks but there aren't any afaict.
