Fix and improve tendermint withdraws

[smk762]

This PR adds a warning for Tendermint withdrawals, and adjusts the layout of the send form to include optional IBC channel ID input.

To Test:

• Login and go to send some Tendermint coins
• See warnings about IBC transfers to CEX
• Send tendermint coin with non-IBC transfer (same chain/address format)
• Send tendermint coin with IBC transfer but without custom IBC channel
• Send tendermint coin with IBC transfer and with custom IBC channel
• Confirm link to IBC channel info working
• Test transactions with some other coins to confirm no regression (with/without custom fees & memos)

thanks for the fix
IRIS withdraws now work fine

Sometimes one of the RPCs returns an error, but sends the tx anyway (bg color of error message is fixed):

idk which of them returns the error, i have this in my config for IRIS:

            {
                "url": "https://iris-rpc.alpha.komodo.earth/",
                "api_url": "https://iris-api.alpha.komodo.earth/",
                "grpc_url": "https://iris-grpc.alpha.komodo.earth/",
                "ws_url": "wss://iris-rpc.alpha.komodo.earth/websocket"
            },
            {
                "url": "https://rpc.irishub-1.irisnet.org"
            }

anyway, this is not related to the fix, but to the RPC endpoint

the time out comes from https://iris-rpc.alpha.komodo.earth, the tx is sent anyway
the other RPC endpoint is even worse, it shows a fee error and does not send anything
guess we need to find some other/more endpoints
what about the ones from https://github.com/cosmos/chain-registry/blob/master/irisnet/chain.json ?

tried a second public RPC and i get same error as with https://rpc.irishub-1.irisnet.org

does our endpoint, https://iris-rpc.alpha.komodo.earth have anything special configured in regards to the txfees?

minimum-gas-prices = "0.001uiris"
enable-fee-suggestion = false
gas-to-suggest = 200000
denom-to-suggest = "uiris"

in app.toml

funny is that swaps work with the public endpoint... on my makers i only have https://rpc.irishub-1.irisnet.org configured... when i use the same on Desktop (also tried a second public RPC) i get the error about the fees on withdraws
it works with our own RPC, even though that one often shows a timeout when sending, but the tx is sent anyway
