Database Initialization & Fixes

This package includes critical fixes ensuring smooth database initialization on Odoo 16 with Python 3.11+.

Module Categories Fix

Issue: missing module categories referenced by ir_module_module.xml during init.

Fix: add the categories to base data (ir_module_category_data.xml).

Impact: DB initializes cleanly; no more External ID not found errors.

Issue: _NamespacePath cannot be +-concatenated with lists (Python 3.11+), breaking addons path handling.

Fix: cast namespace path to list before concatenation:

# BEFORE
addons_paths = odoo.addons.__path__ + [root_path]
# AFTER
addons_paths = list(odoo.addons.__path__) + [root_path]

Impact: runtime stable on Python 3.11–3.12.
