explore_record: Reporting unique OCIDs of large files

[jpmckinney]

e.g. http://standard.open-contracting.org/validator/data/efa21228-0d98-4080-8c4f-ab63db58e1f6

"Unique OCIDs" and "Records Table:" are very long. We should collapse them and have a "See all" link or similar to display the rest.

[jpmckinney]

Since this content can be MBs of HTML, it might even be best to only deliver the HTML once the user clicks "see all" (in above proposal).

See CRM issue 5858, where the very large table causes the user's browser to crash/freeze.

Quick fixes for large files

[Bjwebb]

I've done some work on the releases table in open-contracting/cove-ocds#35, but that doesn't include the "Records Table".

Truncate rows in Records table as well as Releases

[Bjwebb]

Changes to the "Records Table" in open-contracting/cove-ocds#43 are now deployed to https://standard.open-contracting.org/review/

[jpmckinney]

From CRM-5858, the data URL (releases) is https://www.data.gouv.fr/fr/datasets/r/68bd2001-3420-4d94-bc49-c90878df322c Submitting that URL now generates a 5MB HTML file. It takes 3.5mins to generate, but that's a separate issue.

For this issue, the records template still prints all records_aggregates.unique_ocids, so renaming the issue to address that last part.
