[BUG] "Location not found" error message is too generic and provides no user guidance

[Shrutii-Rai]

Description

When an invalid location is entered in the Climate Risk Analyzer and "Analyze Climate Risk" is clicked, the error shown is just a plain red box with "Location not found." , no icon, no helpful guidance, no indication of which field is wrong.

To Reproduce

1. Go to the Analysis page
2. Enter an invalid combination (e.g. City: "shruti", State: "rai", Country: "india")
3. Click "Analyze Climate Risk"
4. See the generic red error box appear

Expected behavior

• Error message should say: "We couldn't find this location. Please check your city, state, or country spelling."
• A warning icon (⚠) should appear inside the error box
• The City input field border should turn red to help guide the user
