Add Web NFC support for writing and scanning NFC tags

[alangibson]

• Add NFC scanning to the existing barcode scanner page
• Add NFC tag writing to the part tools section
• Protect existing tag contents by default and require explicit overwrite confirmation
• Hide NFC controls on unsupported or insecure clients

Web NFC currently only works on Chrome on Android when served over HTTPS.

Hey thanks for the PR.

What is the usecase for this?

Users can write the scan link of Part-DB onto an NFC tag, so they can be opened with a tap?
I guess there are no parts with manufacturer or distributor NFC tags.

Thanks for the great project. I'm dedicating a significant part of my life to organizing my disaster zone of an electronics lab and this is exactly what I need.

My use case is affixing NFC tags to individual containers in assortment boxes. These boxes are already labeled with what's in them. See this: https://makerworld.com/en/models/769441-label-generator-gridfinity-bin?from=search#profileId-705079

It is possible to put a sticker with barcode on the side of the container. However, being 3d printed, the stickers don't stick to sides well. I'm pretty sure the will fail over time as individual boxes are moved around.

The bottoms are smooth and stickers stick well, but barcodes are inconvenient there. Hence I went with stick on NFC tags.
