fix: correct hemisphere signs for Pacific territories airports (#729)

Corrects coordinate signs for 8 airports in US Pacific territories:

American Samoa (should be Southern Hemisphere):
- FAQ (Fitiuta): latitude corrected to negative
- PPG (Pago Pago International): latitude corrected to negative
- Z08 (Ofu): latitude corrected to negative

Mariana Islands/Guam (should be Eastern Hemisphere):
- GRO (Rota International): longitude corrected to positive
- GSN (Saipan International): longitude corrected to positive
- TNI (West Tinian): longitude corrected to positive
- TT01 (Pagan Airstrip): longitude corrected to positive
- GUM (Guam International): longitude corrected to positive

These airports were incorrectly placed in opposite hemispheres, causing significant geographic errors (e.g., showing in Indian Ocean instead of Pacific).
