Orderbook Readability Issue #1330

[18c83fd3-25ea-4ed9-8205-2abeff9b3883]

Updated Orderbook UI for better readability:

• The table is using monospace font, which makes the numbers align better
• All values are displayed in satoshis (sats)
• Numbers are formatted with commas (e.g., "100,000 sats" instead of "100000 sats")
• The column headers consistently use "sats" as the unit

EXAMPLE:

Thanks for the PR.

A couple things from just a superficial look.

• The fidelity bond value should not be in sats, but its own arbitrary unit. I think this is important or users might think that's the actual value of the locked UTXO, which is not. It's the result of the bond formula.
• Is there a need a to add a sample orderbook? Not sure.
• I don't think it's useful to repeat sats after every value, it seems better to just have it in the headers.
