bug(Notes): Remove default access level from global notes

[Kruptein]

Notes can be shared with other players using the access tab. Sometimes you just want to quickly share with all players and the 'default' access row that we currently have is very nice for that.

For local notes this is very intuitive. It shares whatever access rights the default row has with all players in the campaign.

For global notes this is less intuitive, because there is no real link to a campaign and thus to a set of default players. The global note might be used in multiple campaigns with a variety of players. It has no home campaign.

This leads us to the present day where a global note with default access actually is shared with all users on the server. This is not really ideal, so this PR removes the default access row for global notes. Where necessary share global notes with specific users. The access UI has an interaction label to select all users in the current campaign, so it should not really impose much trouble.

It's currently resolved without a migration and simply hard filtered on the server.
