[Added] 3 new modes (less useful but still nice to have):
- Base > Call
- Previous Call > Call
- Call > base (full mileage)
[Added] When a base is selected, the route on the map and input fields are now updated automatically when the browser tab is active and user has moved more than 0.5km.
[Changed] Use flag (⚑) to represent “Current Call” for visual clarity.
