feat:add map language control

[rohhann12]

Starting Step to close #384

🛠️ Fixes Issue

The issue was the map would show the names of the countries in the format of their own local language (eg- middle eastern countries name would be shown in arabic).

👨‍💻 Changes proposed

-src/components/map/index.tsx
-src/components/map/map-language-control.tsx

📄 Note to reviewers

Approach:
The Shortbread OSM vector tiles use text-field: "{name}" on all symbol layers for label rendering. The tiles also provide name_en and name_de as alternative name properties.
I added a MapLanguageControl component that:

1. Iterates over all symbol layers in the current map style
2. Swaps the text-field layout property between {name}, {name_en}, or {name_de} based on user selection
3. Persists the choice in localStorage so it survives page reloads and style switches (restored via onLoad and onStyleData events)
   Currently limited to 3 languages since that's all Shortbread tiles support. This can be extended once we move to Maptiler tiles which offer broader language coverage.
