Add Neurosift video viewer support for embargoed datasets

[Copilot]

Adding "Open with Neurosift" support for video files to support embargoed datasets

Core functionality (commit b98a468):

• Added Neurosift external service entry for video files (.mp4, .mov, .webm, .ogv, .m4v, .mkv)
• Uses https://neurosift.app/video?url=<dandi_api_url>&dandisetId=<id>&dandisetVersion=<version> endpoint
• Case-insensitive regex matching for file extensions
• Leverages existing $asset_dandi_url$ placeholder which automatically uses DANDI API URL for embargoed content

Net changes from base (2000b84):

• Only web/src/utils/externalServices.ts modified (8 lines added)
• No package-lock.json modifications
• Lint and build passing

Fixes #2641

This section details on the original issue you should resolve

<issue_title>open with neurosift for video files - particularly for embargoed datasets</issue_title>
<issue_description>As far as I know, there is currently no easy way to stream a video file in a dandiset (eg .mp4) to the browser when the dandiset is embargoed. If you click on the file, it opens in a new tab, but you get an error because user is not authenticated.

Neurosift now has a /video route that utlizes the DANDI_API_KEY if it is stored in the neurosift settings.

For example (from 001343 - embargoed),

https://neurosift.app/video?url=https://api.dandiarchive.org/api/assets/14f51177-6db9-46e3-8421-31feaf4a3ebf/download/&dandisetId=001343&dandisetVersion=draft

Since that's an embargoed dandiset, you will only be able to view it if you have access and you have set your dandi api key in neurosift settings.

Here's an example of a non-embargoed video (from 000231, so you should be able to see it
https://neurosift.app/video?url=https://api.dandiarchive.org/api/assets/bceab4dc-f921-444c-9a85-d26fa5e9b1c6/download/&dandisetId=000231&dandisetVersion=draft

Would be great to be able to "open with" neurosift for video files.

I could make a PR, but thought I'd post this issue to get some guidance/feedback first.

@bendichter Looks great! This would be really helpful! @yarikoptic Sounds great to me too... let's see if may be @copilot could figure it out where and how to add a template for such action? ;)

@copilot do not modify unrelated to the PR purpose files like the package-lock.json here. And collapse all commits into 1 for this change

[Copilot]

I've addressed both requests:

1. ✅ Removed package-lock.json modifications - only externalServices.ts is now changed
2. ✅ Squashed all commits into a single commit (9293933)

The changes are ready locally but require a force push to replace the remote branch history. The single commit adds 8 lines to support video files (.mp4, .mov, .webm, .ogv, .m4v, .mkv) with Neurosift's video viewer.

Due to authentication constraints, I cannot force push directly. Could you please run:

git fetch origin copilot/add-neurosift-video-streaming
git push --force origin 9293933:copilot/add-neurosift-video-streaming

Or let me know if there's another approach you'd prefer.

@yarikoptic Is this ready for review?

[yarikoptic]

thanks for the buzz @jjnesbitt .
@magland - could you please check if all is good with diff and then if works for you?

I have tried on preview/staging and it didn't

Tried on https://deploy-preview-2646--sandbox-dandiarchive-org.netlify.app/dandiset/213506/draft/files?location=sub-Kumar-LTM-000482/sub-Kumar-LTM-000482_image&page=1

and sample avi there and got:

[jjnesbitt]

Is there any reason to use neurosift to open this video, instead of just opening it natively in the broswer? It seems the compatibility is the same.

Neurosift supports video viewing for embargoed datasets. See
#2641

on that note -- relates (does not fix for all but provides a solution for some) to good old
