Devlog 16

Finally device manager is ready to go.

• Refactored frontend side logic for key-sync to work with new API
• Fixed bugs, improved error handling (so error message is not misleading)
• Removed .idea folder from repo
• Introduced mossy-reactor (way to test micro-services with their dependencies without deploying them to main before tests)

Now it’s time to work on frontend features + design (typography, colors, globals <– boring stuff ://)
