Changes

• Migrates feature settings, feature value and create feature to typescript components
• Migrates Row / FormGroup to fix imports
• Simplifies interface around the create feature modal, this will eventually mean the RTK/redux store no longer needs to create new objects
  • Editing project/feature related stuff is adjusting the ProjectFlag with a single onChange
  • Editing the remote config, enabled state and MV percentages is adjusting a FeatureState with a single on Chnange
• Minor: add tag button same height as tags
