fix: respect geo-location settings when creating notes from templates

[sh1vam31]

Fixes #118

Notes created using templates did not include geo-location information (latitude, longitude, altitude), even when the "Save geo-location with notes" setting was enabled in Joplin preferences.

Fix

Added a new utility src/utils/geolocation.ts that:

1. Reads Joplin's note.saveGeolocation global setting
2. Fetches current GPS coordinates via navigator.geolocation
3. Returns null gracefully if the setting is disabled or permission is denied

Updated src/actions.ts to attach latitude, longitude, and altitude
to the note payload when geo-location is enabled.

Testing

• Enabled "Save geo-location with notes" in Joplin Preferences → Note
• Created a note from template via Tools → Templates → Create note from template
• Verified via Joplin REST API that the note has real GPS coordinates:
