feat: add fusion_tasks module for field service management

Standalone module extracted from fusion_claims providing technician
scheduling, route simulation with Google Maps, GPS tracking, and
cross-instance task sync between odoo-westin and odoo-mobility.

Includes fix for route simulation: added Directions API error logging
to diagnose silent failures from conflicting Google Maps API keys.

Made-with: Cursor
