funding_satoshis values above the total bitcoin supply were not rejected during open_channel/accept_channel negotiation and would later cause libwally to fail and openingd to crash during commitment transaction construction. Reject such funding_satoshis values immediately so that the negotiation terminates gracefully. Fixes: #9225 Changelog-Fixed: `openingd` no longer crashes when a peer opens a channel with a `funding_satoshis` value greater than the total bitcoin supply.
