Add optional name to emission

As user, I want to be able to customize an emission by naming it :

[ ] the optional name field, working as a toggle, should appear above "Add this emission" - 250 characters max
[ ] the input and the toggle components should be tested and in the storybook
[ ] emissions screen should be update and display the name if there is one, in the emission title - force to be displayed in one line
[ ] if no name, emission titles in emissions screen should display the name of the emission, not the category
[ ] name should be displayed in emission screen

Design :
