refactor: rename api-hooks.ts to apiHooks.ts for consistency

- Renamed api-hooks.ts to apiHooks.ts to follow camelCase convention
- Updated all 21 import statements across the codebase
- Maintains consistency with other non-component files (apiClient.tsx, useAuthReady.ts, etc.)
- Follows established naming pattern: PascalCase for components, camelCase for utilities/hooks
