[x] On the custom priority modal, Enter amount in sats subtitle is vague, the user does not know whether we are asking for total number or sats or sat/vbyte. The subtitle should rather be: Enter amount in sats/vbyte
[x] Change "Decide how fast you want the sats" to "Decide how fast you want to send sats", as we are sending sats and not receiving them.
