[Modifications] Consolidate the two location services

[RUKAYAT-CODER]

Overview

src/services/location.ts and src/services/locationService.ts both exist, alongside src/store/locationStore.ts, src/hooks/useLocation.ts (7 type errors) and src/utils/geoUtils.ts. There are also two test files: src/__tests__/services/locationService.test.ts and src/services/__tests__/locationService.test.ts — themselves duplicated across two directory conventions. docs/location-strategy.md describes one design.

Specifications

Features:

• One location service
• One test location, following the repository convention
• The documented strategy matching the implementation

Tasks:

• Diff location.ts against locationService.ts and identify the live implementation
• Merge unique logic and delete the redundant module
• Consolidate the two test files
• Fix the seven type errors in src/hooks/useLocation.ts
• Update docs/location-strategy.md

Impacted Files:

• src/services/location.ts
• src/services/locationService.ts
• src/hooks/useLocation.ts
• src/store/locationStore.ts
• docs/location-strategy.md

Acceptance Criteria

• One location service remains
• Location tests live in one directory
• The hook type-checks
