[Feature]: Show fee rate when you send bitcoins, not just the fee amount

[limpbrains]

Describe the problem

I want to check if bitkit creates a tx with right fee rate. Compare it to the mempool.space or other service.
I can't, because it shows me the fee amount (like 1000 sats) and not the fee rate (7 sats/vbyte)

Describe the solution

Show sats/vbyte
