Smol UX Fixes

[kilrau]

As just discussed:

• [x] rename "Auto" to "Autoswap"
• [ ] delete autoswap config list view
• [ ] Instead autoswap config should be shown pre-populated when cklick "Autoswap" button. Wallet with autoswap configured should be shown. Values are locked with edit and delete button. Every wallet only can have one autoswap config.
• [x] Move into "Advanced":
• optional "Balance to be kept in wallet (sats)" and delete "+free reserve" wording
• optional fee "Claim tx sat/vbyte"
• optional "Min swap size (sats)"

i disagree with 2. and 3. if you have many swap and many wallets i will prefer the list to have an overview

i can add a edit button to the list though, that is ok
