Add min value for hours worked input field on submit work form

[arku]

Description

Currently, we're not validating the hours worked input field. So, a user cannot enter negative numbers though it doesn't make sense. This PR adds a minimum value of 0.25 to the input field.

Note: This is a really minor thing as an average gitcoiner wouldn't enter negative numbers but it was bugging me so I decided to submit a patch.
