Some Loading optimizations

[dartcafe]

• Some async component loading, to reduce bundle sizes and load times
• Async loading of route components
• Set vote early and do not wait for API response to give a faster user feedback (affects huge polls)
• Import lib exports explicit to reduce bundle sizes
• Code maintenance
  • refactor store types
  • import types as types
  • remove index.ts|.js from imports
  • remove .ts|.js extensions from imports
