UGC requirements

• [ ] Show community guidelines when publishing (always) or commenting for the first time (once), and tell users they agree to these when doing so (similar to odysee.com): https://odysee.com/@OdyseeHelp:b/Community-Guidelines:c.

• [x] Add the ability to block channels. Use wallet muting function or implement commentron blocking (mute would be faster). On channel list, add Odysee creator settings link? https://odysee.com/$/settings/creator

• [x] Add ability to report comments. Should be able to block channels via comments also.
