fix(api): unlist removed validator profiles

[onmax]

Summary

• add is_listed flag to validators
• validators present in the bundled profile list are listed; validators removed from that list (or discovered without a bundled profile) are unlisted
• unlisted validators keep row/history, but profile metadata is neutralized
• only-known=true now uses listed state (with fallback for legacy NULL rows)
• expose isListed on validator responses and unlistedActiveValidators on status

why not just removing it from the db?
if validator not in the public/validators then remove from db

we track by default all validators in the db... also i am afraid of breaking the wallet somehow. Adding an additional field seems the best way for backward compat

adding an additional param requires more work in the wallet, just dont mark removed validators as known?
the validator is still active, it's just not a pool anymore

the validator does use another method to retrieve the validators from the blockchain. they don't use our api. Just to merge their addresses with the logo, description and score.
