Document generation module: templates with own text (structure reference
and source stand documented per template, no licensed full text in the
repo), fill fields resolved from hr data (company, employee, hr.version
stand) plus wizard input, preview rendering and PDF/HTML attachment via
the generic report layout.
- templates: pilot set for the general-AT track formulated as own text
after the KB muster structure (lb-bes-09, lb-bnd-55, lb-bnd-52/62,
lb-end-35), legal status per template marked as draft
- rendering via convert_inline_template_to_qweb + ir.qweb (t-out
auto-escapes values) — deliberately not mail.render.mixin inline
engine, whose expression whitelist blocks werte[...] placeholders for
non-template-editors
- wizard resolves hr.version by date_version at the reference date;
PDF falls back to HTML attachment without wkhtmltopdf
- security: ir.model.access (hr user read / manager write) + company
rule; 8 tests, suite 236/236 green on a fresh -i database run
