Beta page - support non-instagram sources

[lemeryfertitta]

In the beta_links table, less than 1% of the links are from non-instagram sources. The only other sources I've seen so far are TikTok and Kaya. In theory, this could be supported by Climbdex, but given the rarity of these beta sources, this seems very low priority.

For now, beta_links not matching https://www.instagram.com% are filtered out.
