Remove block list apis

[jessopb]

To make more progress here, https://github.com/lbryio/lbry-desktop/issues/7663 remove calls and code that call list_blocked and list_filtered on startup.

• Remove api calls (on startup)
• Remove blocking reducer/actions/selectors
• Remove unnecessary inputs to "banstate" which also processes comment moderation which we're keeping

Latest version's text field includes some text from the blocklist publisher about the reason for the block. It would be good to include this text field (for now). Maybe include a space for a 'message' below the app's existing text.

Is it cause we moving away from hardcoded list to HUB side blocklist?
