DPL-370 Labware destruction UX improvements [C=M]

[KatyTaylor]

User story
There were a number of UX improvements requested during UAT of the labware destruction feature #338

I have grouped them together in this story as each of them is probably quite small, and it might help to think about them together.

Acceptance criteria
To be considered successful the solution must allow:

• Source labware box lines are numbered (easier for user to review the list before submitting)
• Display errors / feedback messages for different labware in more user-friendly format (currently difficult to read if multiple labware are scanned in one go, as all errors appear on the same line)
• Show confirmations for the labware successfully destroyed. (currently only failures are shown and it makes it hard to know what was successful)
• Retain the list of labware that were scanned on-screen once you press submit. (easier for user to review the list and check they did the right thing -- ideally the list would use colours and icons to indicate which were successful and which failed to be destroyed)

N.B. It would be good if these can be implemented generically for all Asset Audits actions - UX improvements for everyone! There's nothing specific to the labware destruction feature here, as far as I know.
