When custom badge is uploaded we allow to enter custom URL to link it to. We need to make it configurable for operator and allow option to select user's contexts/orgs within the app.

• 1. add selector combobox to choose user's contexts or organizations instead of custom link.
• 2. Setting to "Allow links to external resources" in Badge settings for Operators. If allowed add option to input custom link.
