Add formatTraceData utility and integrate into logging

- Introduced a new utility function `formatTraceData` to standardize the formatting of trace data for logging purposes.
- Updated various modules including auth, database, and stats manager to utilize `formatTraceData` for improved log clarity and consistency.
- Added new schemas for printer profiles and filament profiles to enhance the data model.
- Implemented tests for session authentication to ensure robust functionality and error handling.
