Enhancement: Use the same URL layout as Archive.org for viewing ArchiveBox Snapshots https://archive.org/web/<URL>

[pirate]

To visit an archived version of a website (or archive it automatically) on Archive.org, one can just visit http://web.archive.org/web/https://example.com/ and it will redirect to http://web.archive.org/web/20230116145642/https://example.com/ (or whatever the most recent snapshot timestamp is).

To really emobdy the tagline "ArchiveBox is a self-hosted version of archive.org" we should properly support their URL scheme too.

e.g.

• https://demo.archivebox.io/web/https://example.com should redirect to the most recent snapshot https://demo.archivebox.io/web/20230116145642/https://example.com

  • note: support both the ArchiveBox-style timestamp in unix timestamp format e.g. 1673919713 or the Archive.org-style 20230116145642 format and truncated forms 2023, 202301, 20230116
  • note: also support visiting using snapshots using ulid uuid instead of timestamp as slug, e.g. https://demo.archivebox.io/01ARZ3NDEKTSV4RRFFQ69G5FAV/...
  • note: support auto prefix-matching slugs so that 2023 matches 202301, 20230116, 20230116145642 automatically, and 01AN4Z07BY matches 01AN4Z07BY79KA1307SR9X4MV3 automatically

  Full spec:

https://demo.archivebox.io/web/<SLUG> where SLUG can be:
- an original URL, with or without scheme, e.g. https://example.com/index.html, 'example.com/index.html' ➡️ redirect to most recent snapshot for https://demo.archivebox.io/web/20230116145642/https://example.com/index.html
- an ArchiveBox snapshot UUID in ulid/spec format 01AN4Z07BY79KA1307SR9X4MV3/index.html or timestamp prefix 01AN4Z07BY/index.html ➡️ redirect to that exact snapshot https://demo.archivebox.io/web/20230116145642/https://example.com/index.html
- an ArchiveBox snapshot timestamp in YYMMDDHHMMSS, shortened forms like YYYYMM, or unix timestamp format e.g. 20230116145642/index.html or 202301161456/index.html, 202301/index.html, 1673919713/index.html ➡️ redirect to most recent snapshot matching that prefix https://demo.archivebox.io/web/20230116145642/https://example.com/index.html

Subtasks:

• adds derived ulid field + migration to coalesce old uuid and timestamp fields into new ulid format (+asserts all snapshot timestamps are valid and are between 1900 and 2100 AD)
• update admin and index UI to show ULID of old UUID4 xxxx-xxxx-xxxxxxx format, add ULID diagram in docs breaking it down into timestamp and randomness
• create disambiguation page to show all the matching results for a given SLUG if it's the prefix for multiple possible snapshots
• reject Snapshot UUIDs being created that begin with 0, 1,2,htt to make prefix-matching faster and less error prone (avoids clashing with 199x*/20** year, 1* unix timestamp, 01* ULIDs, or http(s?) URL slug prefixes)
• add docs examples on how to truly "self-host your own archive.org", add screenshot side-by-side of URL bar examples for visiting snapshots on Archive.org and demo.Archivebox.io
