Add pattern intensity map with gradient visualization

[Ksheetiz-24]

In the Landscape Explorer web app on the /kyl_dashboard route, the left sidebar contains two tabs: Filters and Patterns.

Under the Patterns tab, a new button should be introduced that allows users to visualize pattern intensity across MWS polygons. When clicked, the button should open a popup/modal containing a map view.

The map should display all MWS polygons with a color gradient based on the number of patterns matched:

• Green → Safe / no stress patterns
• Yellow/Orange → Moderate number of stress patterns
• Red → High number of stress patterns

This visualization will help users quickly identify high-stress and low-stress areas.

Steps to Reproduce

1. Navigate to /kyl_dashboard
2. Select State, District, and Tehsil
3. Open the Patterns tab in the left sidebar
4. Observe that no pattern intensity map is currently available

---

Expected Behavior

• A new Map View (or similar) button is available under the Patterns tab
• Clicking the button opens a popup/modal with a map
• Each MWS polygon is rendered using a green → red gradient
• Gradient intensity is based on the number of patterns matched for each MWS

---

Actual Behavior

• No visualization exists to show pattern intensity across MWS polygons

---

Suggested Improvement

• Add a popup-based map view under the Patterns tab
• Apply gradient styling to MWS polygons based on pattern count
• Include a legend explaining green → red intensity levels

---

Acceptance Criteria

• A new button is available under the Patterns tab in the left sidebar
• Clicking the button opens a popup/modal containing a map view
• The map displays MWS polygons
• Each polygon is styled using a green → red gradient
• Gradient intensity is based on the number of patterns matched for that MWS
• Green represents safe / no stress patterns
• Red represents a high number of stress patterns
• A legend is visible explaining the color gradient
• Map is readable at default zoom levels
• Popup can be closed easily without affecting the main map state
