Change baby weight input to grams instead of kilograms.

This change is required in the following screens:

1. Infant (Newborn) Registration - Weight at Birth (kg)
2. Child Registration - Weight at Birth (kg) – only view
3. HBNC  - Baby Weight (kg): This a new feature & No existing data so directly change the to Grams and save
4. HBYC  - Baby Weight (kg): his a new feature & No existing data so directly change the to Grams and save

Currently Weight is captured in kgs, so this should be changed to Grams. And this should not impact the existing data (Weight already captured).

First check the data type in database is supporting for Kgs or Grams

If database is supporting for Kgs, then in the UI screen Weight field should support for entering values in Grams and then convert Grams to Kgs and sync to db

In view screen, to show Weight convert Kgs to Grams
