store & reference pattern by name (#1766)

## Description:

Store pattern by name instead of value. The worker replaces the pattern
name with it's base64 when joining. This ensures the client & server are
never out of sync after patterns are updated.

* removed resizeObserver on the territory modal, it was causing some
race conditions, and the modal is not resizable so it's unnecessary.

* Moved PatternSchema to CosmeticSchema
