Fix: Add bounds field to source editor UI

Closes #1037

---

Problem

Raster and vector sources support the optional bounds parameter in the MapLibre style specification: a 4-value array [west, south, east, north] that defines the geographic bounding box of a source. Although Maputnik correctly reads and applies this value from JSON, it was never shown in the source editor UI. That meant users had to switch to the raw Code Editor to view or edit bounds.

---

Fix

Added a bounds input field to both source editor types in ModalSourcesTypeEditor.tsx, following the same pattern used for minzoom and maxzoom:

• Four separate numeric inputs for west, south, east, north
• Optional field behavior: if bounds is not present in the JSON, the inputs stay empty
• Uses the existing default world bounds value [-180, -85.051129, 180, 85.051129]
• Applies to both TileURLSourceEditor and TileJSONSourceEditor

---

Screenshot

bounds values [140, 20, 150, 30] are now visible and editable in the source editor UI, right below Max Zoom

---

Files changed

File	Change
ModalSourcesTypeEditor.tsx	Added bounds to TileURLSourceEditorProps and rendered a FieldArray after maxzoom
ModalSourcesTypeEditor.tsx	Added bounds to TileJSONSourceEditorProps and rendered a FieldArray after the URL field

---

Testing

• Load a style with bounds set — all four values appear correctly in the source editor
• Load a style without bounds — fields remain empty and the UI does not crash
• Edit bounds in the UI — changes are reflected in the JSON
• npm run lint passes
• npm run build passes
