feat: Improved nutrition input

[g123k]

Hi everyone!

The current screen was really irritating me, so I changed a number of things.
Video (offline, due to the server):

ScreenRecording_01-21-2025.14-02-40_1.MP4

No more Switch

Everything is a dropdown, so we can see all the options

Direct access to the photo

If no photo is available, the dedicated screen is opened

Add a nutrient in a modal sheet

The + button stays at the top of the screen (sticky header) 🤌

Bugfixes

There are no more multiple cursors 😮‍💨

Help for everything

TODO: needs to be done

There's even an easter egg

Where is it?

Very nice, but I would add a second way to add a nutrient at the bottom of the table, with an explicit text.
In the future, we could have additional buttons/toggles/nudges at the bottom for edge cases : the product is a mineral water, the product is alcoholized, chocolate, supplements, either manual, or category driven (automatically more fields)

Ok, I will bring the button back, but it's so annoying to scroll down everything single time
