fix: resolve remaining Docker integration test failures

Browse Source 
Fixed 2 remaining test failures:

1. NODE_DB_PATH environment variable test:
   - Issue: Null byte handling error in shell command
   - Fix: Use existing getProcessEnv helper function that properly escapes null bytes
   - This helper was already designed for reading /proc/*/environ files

2. User switching test:
   - Issue: Test checked PID 1 (su process) instead of actual node process
   - Fix: Find and check the node process owner, not the su wrapper
   - When using --user root, entrypoint uses 'su' to switch to nodejs user
   - The su process (PID 1) runs as root but spawns node as nodejs

Also increased timeouts to 3s for better CI stability.
