Addition of a search functionality in the SOH page of Stock Management

Hi everyone,

Malawi’s team has reported this issue and I think that it’s really worth adding to the system.

Description
Users of the system have raised a concern about having to navigate to many pages before locating a particular product when they visit the Stock on Hand page in Stock Management. This is a tedious process that can be frustrating. Please add a search functionality within the page to allow a user to type a product name and search for the product. Locating the product by code would also be useful.

So basically what we need to do is to add filter on this page that would work similar to other pages so filter the table with the given criteria.

@joshzamor @ibewes What do you think about it?
