Allow to add in a box: individual samples

[diegoliberman]

When the box's purpose is Other, we should allow to add existing samples to the box.

Story

As UCSD, I want to create a custom box for transferring some specific samples, so that I can keep track of what happened with these samples.

Acceptance criteria

1. I select the Other purpose.
2. I can see a field for entering a sample ID, I'll call this field Find ID.
3. If 1 or more non-QC samples match with the partial ID of the previous step, I can confirm which one I want to add and it gets added to a list of samples being added to the box. After confirming, the focus moves back to the Find ID.
4. I can continue adding as many samples as I want.
5. If a non-QC sample matches with the complete ID of step 2, the sample gets added automatically and the focus is placed again in the Find ID.
6. I can save the box.
