Pasting 956894 in the latitude field of a new site crashes the app

956894

Was supposed to be 59.956894, but copying did something weird. App shouldn't crash anyways…

Fixed in commit 19d817d. Merged to staging and deployed to https://staging.linksim.link.

The app now validates latitude (-90..90) and longitude (-180..180) ranges, showing user-friendly error messages instead of crashing when pasting malformed coordinates like 956894.

Real-time validation added in commit d105094. Merged to staging and deployed to https://staging.linksim.link.

The app now:

• Validates coordinates in real-time as you type
• Shows error messages immediately on the input fields
• Only updates the map marker when coordinates are valid (-90..90 lat, -180..180 lon)
• Prevents crash when pasting invalid values like 956894
