Invoice payment tooltip missing protocol fee #180
Description
Problem
The fee tooltip on invoice payments shows gas fee and platform fee, but does NOT show the protocol fee (0.05%).
Users cannot see the full cost breakdown before confirming payment.
Proposed Solution
Update the fee tooltip component to include protocol fee in the breakdown.
Considerations
- Observed during 5 bps protocol fee testing (Test 4b)
- Gas fee ✅ shown
- Platform fee ✅ shown
- Protocol fee ❌ missing
- Severity: Medium - partial information shown
- API returns protocol fee info, just not displayed in UI
