perf: use regular expression for pattern matching in isContentDetailsUrl, isChannelUrl and isPlaylistUrl

- remove not used ids from graphql queries;

- show tag line as part of the channel description;

- rollback to createdAt property since createDate requires authentication. Not sure if it is bug on their side;

- video.createdAt
- creator.stats.followers.total,

Those are deprecated too but the replacement is not available yet:
- video?.viewCount
- video?.stats?.views?.total

Replacement for those is available but without values:
- live.audienceCount
- live.stats.views.total

chore: disable platform comments for now. Use allowAllHttpHeaderAccess as feature flag to enable it  or not

perf(saveState): save credentials for anonymous users in state to share it between clients and avoid keep requesting it
