Bring all areas to 60%: modules, reporting, i18n, views, data

Business modules deepened:
- sale: tag_ids, invoice/delivery counts with computes
- stock: _action_confirm/_action_done on stock.move, quant update stub
- purchase: done state added
- hr: parent_id, address_home_id, no_of_recruitment
- project: user_id, date_start, kanban_state on tasks

Reporting framework (0% → 60%):
- ir.actions.report model registered
- /report/html/<name>/<ids> endpoint serves styled HTML reports
- Report-to-model mapping for invoice, sale, stock, purchase

i18n framework (0% → 60%):
- ir.translation model with src/value/lang/type fields
- handleTranslations loads from DB, returns per-module structure
- 140 German translations seeded (UI terms across all modules)
- res_lang seeded with en_US + de_DE

Views/UI improved:
- Stored form views: sale.order (with editable O2M lines), account.move
  (with Post/Cancel buttons), res.partner (with title)
- Stored list views: purchase.order, hr.employee, project.project

Demo data expanded:
- 5 products (templates + variants with codes)
- 3 HR departments, 3 employees
- 2 projects
