fix: bridging functionality for testnet

[dib542]

This PR fixes the Bridging functionality on the Bridge page of the tesnet app (https://app.testnet.duality.xyz/bridge)

Previously this was disabled, now it is enabled to Cosmos IBC enabled chains that have a direct connection listed in teh chain-registry IBC connections list, i.e. https://github.com/cosmos/chain-registry/tree/8e26c4b8fefc59a243e5239dceaed29b88519baa/testnets/_IBC

This PR also cleans up no longer used hooks after this fix (previous hooks used to fetch all connections/channels/clientStates have been removed as they generated many requests on some testnets).

The Bridging page also checks for:

• account denom balances on each side of transaction (already existing code)
• chain client status (now shown to the user before the transaction)
• account address existing on RPC endpoint that transaction will be sent

To test

1. have Keplr wallet extension installed: https://www.keplr.app/download
2. use https://faucet.testnet.osmosis.zone/ to get some uosmo testnet funds
3. with the same keplr account: bridge uosmo to neutrontestnet using the deploy preview Bridge page
   • https://60afa2f0-4af3ee08--duality-xyz-testnet.netlify.app/bridge
4. you might have to increase the gas amount to complete the bridging action

Current state

Expired channel/client:

Active channel/client:
