[QA] Affiliates: commission calculation unclear (flat vs percentage)

[eltociear]

Bug Description

Commission model is confusing. Some offers use commission_type "flat" with commission_flat_sats, others use "percentage" with commission_rate. No documentation on how actual payouts are calculated.

Examples

• iTrustCapital: flat, 40000 sats per conversion (clear)
• Gemini: flat, 10000 sats per conversion (clear)
• Spotify: percentage, 20% rate, price_sats=12 (20% of 12 = 2.4 sats?)
• Mercury: percentage, 20% rate, price_sats=0 (20% of what?)

Issues

1. When commission_type is "percentage", the base amount is unclear
2. price_sats=0 with percentage commission means 0 payout
3. No estimated_payout or calculated_commission field for affiliates

Suggestion

Add an estimated_commission field or tooltip showing what affiliates will actually earn per conversion.
