Implement display_uri event for FCL Ethereum provider

[jribbink]

Wagmi depends on the display_uri event, so we must implement this for our WC wallets. This will probably require changes to the currentUser.authenticate function. Probably something along the lines of passing down a onDisplayUri handler which disables the default modal.

Fcl-wc already has a pairingModelOverride option which may be able to be leveraged, however this is only configurable at initialization and not on a per-request basis, so changes should be required regardless.
