🔧 Fix import paths: Remove non-existent prelude module references

- Fixed 101+ files importing common::types::prelude which doesn't exist
- Changed all imports to use common::types directly
- Fixed BarEvent duplicate import in data/src/types.rs
- Aligned all imports with canonical type system in common crate

common/src/lib.rs
