refactor notifications to MVC: extract templates, context, and renderer
- Move all email layout to Jinja2 templates (4 files: admin_new,
admin_update, parent_confirmation html+txt)
- Extract pure helper/context-builder functions to context.py
(format_types, calculate_age, format_dob, calculate_monthly_fee,
format_days, build_admin_new_context, build_admin_update_context,
build_parent_context)
- Move i18n label strings out of Python into YAML locale files
(i18n/de.yaml, i18n/en.yaml) — admin-editable without code changes
- Add renderer.py as thin Jinja2 wrapper (render_template)
- Reduce notifier.py to routing + SMTP dispatch only
- Update tests to call context functions directly and render
templates via renderer instead of calling private builder methods
- Add jinja2 and pyyaml as explicit dependencies in pyproject.toml
