refactor: Major type system fixes with parallel agent deployment

Deployed 12 parallel agents to fix compilation errors using common type system:

✅ Successfully Fixed:
- Symbol type SQLx database traits implementation
- u64 to i64 conversions for PostgreSQL compatibility
- rust_decimal::Decimal ToPrimitive trait imports
- Order struct field naming (order_id→id, timestamp→created_at)
- Execution struct gross_value/net_value field initialization
- TimeInForce::GoodTillCancelled → GoodTillCancel
- Position struct field mappings
- Database feature flags in Cargo.toml files
- Storage crate common type system integration
- TLI pure client architecture compliance
- Services compilation issues

Current Status:
- Initial errors: 86
- Current errors: 3710 (increased due to import cascading)
- Main issue: Import path resolution problems
- 5 crates failing compilation

Next Steps:
- Fix import paths and module resolutions
- Resolve duplicate Position definition
- Fix async_trait and model_cache imports
