Replace infrastructure costs with actual domain invoice data

Browse Source 
Start ledger January 2025. Record coulomb.social (3.75 EUR/mo) and
coulomb.pro (3.00 EUR/mo) as per-domain expense rows. Remove Bubble and
placeholder overhead. Add infrastructure reference catalogs; virtual server
records pending invoice data.
