refactor: continue lint cleanup - 96 more issues fixed

- Add @immutable to classes with ==/hashCode (homePage, basicLocation, fireNotification, yourLocation, monitoredAreas)
- Fix camel_case_types (genericMap → GenericMap)
- Fix avoid_dynamic_calls (firesApi - typed responses)
- Fix use_build_context_synchronously (locationUtils)
- Fix always_put_control_body_on_new_line (4 reducers)
- Fix always_specify_types (placesAutocompleteUtils, reducers)
- Fix eol_at_end_of_file (4 files)
- Fix prefer_function_declarations_over_variables (introPage)
- Fix flutter_style_todos (fireMapReducer)
