[FEATURE] Ability to Mute Content from Bridges and Certain Community Relays

[aaccioly]

It would be great to have a way to mute posts originally written to certain noisy relays like wss://relay.mostr.pub.

Just removing the relay from the user’s relay list isn’t enough as events still get propagated to other relays.

For bridges like Mostr and specific gated community relays enforcing NIP-05 identifiers (e.g., Ditto), the ability to mute events from a NIP-05 domain would be enough. For example, Amethyst could allow muting all content signed by users whose kind 0 events have a "nip05" key containing @mostr.pub.

I’m not sure if a general solution is even possible since not all events are tagged with relay information. Determining the "origin" of an event may not be feasible or even make sense (e.g., a kind 1 note may be blasted to multiple relays simultaneously).

Bounty: 5k sats for nip05 domain-wide muting. 50k sats for a general solution (e.g., a new "Blocked Relays" tab in Security Filters - if a general solution is feasible).

The nip05 filtering was fairly easy to add and I can see use-cases where it helps with filtering out spam or other unwanted content.
