Add QR code generation and scanning to UI

[ml-evs]

Closes #803.

This PR:

• Adds a QR code icon to all refcode displays, which, when clicked, opens a modal showing the QR code for that sample item, with a WIP print button that create a dummy window containing just the QR code.
• The QR codes point to {{ QR_CODE_RESOLVER_URL }}/items/<refcode>, which can be configured. The refcode itself is always parseable from this URL, so datalab-native scanners (such as that described below) can resolve the item without needing to go via the resolver.
• There is also a "Scan QR Code" button at the top of the sample table page (for now) which opens a camera stream and provides file upload for providing a datalab QR code.
• API route argument is added for redirect-to-ui, where the /items endpoint can point itself to the UI, if configured. This is the default redirect used by the purl system.

Potential follow-ups:

• This scanner should do the following:
  • Detect if the sample is from this deployment, and if so, redirect to the edit page directly.
  • Follow the resolver link with JS and get the "real" underlying URL, then present it to the user to click on, if it believes it to be a datalab QR code.
  • If it does not believe it to be a datalab QR code, do the same as above but with a giant warning.
• QR codes should also embed tokens that allow for access of non-private/safety data. This will need updates to the API too.
• The barcode print itself should also allow some info to be printed automatically.

This this is ready when you are @jdbocarsly and @BenjaminCharmes -- I have one comment we can discuss regarding configuration (but probably that can be addressed in another PR before release)

[BenjaminCharmes]

It looks really good! 👏

[jdbocarsly]

looks good! excited to start using this and build on top of it
