Expected Output (from source Pink Travel PDF):

Field	Expected Value
Auftragsnummer	315047
Kundennummer	21736
Rechnungsdatum	17.12.2025
Traveler	Frau Pusphamma Thadathil
Ticketnummer	2760995628

Actual Output (Bug!):

Gesamtbetrag	10.00 CHF	❌ Should be 541.15

Debug Log:

Normalized text: Auftragsnummer:315047 Kundennummer:21736 Rechnungsdatum:17.12.2025
Traveler pattern did not match!
Price validation mismatch: 0 + 0 + 330.15 = 330.15 vs total 10
Flights: 0 found

🎯 Root Cause Hypothesis

1. Text extraction format mismatch: pdf_oxide extracts Label:Value (no space), but regex patterns expect different formats
2. Regex patterns broken in src/parser/extractor.rs
3. Flight segment regex doesn't match normalized text
4. Traveler extraction fails completely
5. Price extraction assigns wrong values
