Address Autocomplete Component & Route #41

[VidurShah]

Implemented address autocomplete component for frontend with full backend API integration. This allows both student and police views to search for addresses with real-time suggestions from Google Maps Places API.

Changes:

Backend:

• Added POST /locations/autocomplete endpoint in location_router.py that accepts { "address": string } and returns autocomplete suggestions
• Created AutocompleteInput Pydantic model for request validation
• Implemented location_router_test.pywith 7 tests covering success cases, validation, authentication, and error handling
• All routes require user authentication (student or police role)

Frontend:

• Created LocationService in locationService.ts to wrap the autocomplete API call using POST requests
• Built AddressSearch component with:
  • Debounced search input (300ms delay)
  • Dropdown suggestions that appear as user types
  • Address selection that locks the input field
  • Clear button (X icon) to reset selection
  • Loading and error states
  • Uses Shadcn UI components (Command, Popover, Input, Button)

Component integrated with mock client for development

Also, changed /backend/scripts/reset_dev.py to match what is in the database - SQLAlchemy fixed itself after that for me, and dev container works appropriately now.

Closes #41

Looks great. Dropdown feels way more consistent now. All I saw was that the party reg form also needed a default, so I just added that myself for time's sake. Thanks!
