debug: add comprehensive diagnostic logging for database initialization

Browse Source 
Following systematic debugging methodology after 5 failed fix attempts.
Adding extensive print-based diagnostics to trace execution flow in Docker.

Instrumentation added to:
- api/main.py: Module import, app creation, lifespan function, module-level init
- api/database.py: initialize_dev_database() entry/exit and decision points

This diagnostic version will help identify:
1. Whether module-level code executes in Docker
2. Which initialization layer is failing
3. Database paths being resolved
4. Environment variable values

Tests confirmed passing with diagnostic logging.
