Add Possibility to Filter: opensats.org/projects

[Arvin21M]

This is about adding filtering capabilities for Listed Projects on opensats.org/projects

Per @dergigi

"...a filter that uses the tags we already have would be great, again that would be nostr/bitcoin/lightning but also wallet/etc - we have that data already... (https://flowbite.com/blocks/application/filter/#advanced-filter-by-keywords) Something like that."

Can be something simple at first, a nostr/bitcoin/lightning filter would go a long way. We have tags defined already, so simply use those.
