feat: Add Nearby Places Locator

[tankerkiller125]

This pull request introduces a new "Find Nearby" feature that allows users to search for and add places of interest near a selected location. The implementation includes a new modal for browsing nearby places, API integration, UI enhancements, and localization support. Additionally, admin settings are added to configure the categories and search parameters for this feature.

Nearby Places Feature Implementation:

• Added a new NearbyPlacesModal component that allows users to search for and add nearby places by category, with support for loading states, error handling, and multi-language labels.
• Integrated the modal into the PlaceInspector component, including a new "Find Nearby" action button (with a radar icon) that appears when latitude and longitude are available. [1] [2] [3]
• Extended the mapsApi with a new nearby method to fetch nearby places from the backend.

Localization and UI Texts:

• Added English and German translations for all "Nearby Places" feature UI texts, including category names, button labels, and error messages. [1] [2] [3] [4]
• Updated icon imports to include the new radar icon for the "Find Nearby" button.

Admin Configuration:

• Introduced admin settings to configure enabled categories, default search radius, and maximum results for the "Nearby Places" feature, including UI state management for these settings. [1] [2]

These changes collectively add a user-friendly way to discover and add nearby places, with customizable settings and full localization support.

Front-end calls a new route /api/maps/nearby but this route does not currently exists, and the PR doesn't include the new backend route

I've changed the target to dev as we are changing the backend architecture. Can you please seek the conflict and resolve them ? I'd be happy to review your pr afterwards
