fix: add/find tab now lookup-only, nav fix, route techs fix

- Add/Find tab: removed check-in card and add-asset form, now pure lookup
- OCR: stop camera after capture, added GPS capture at photo time
- OCR: increased timeout from 8s to 15s to reduce 500 errors
- Nav tab: added GPS prompt + asset search when navigating directly
- Route: include all 26 techs from bookableresource table (not just Shawn)
