Problem

When a template uses {{p var }}, patch_xml strips the enclosing <w:p>
(including w:pStyle / alignment) before Jinja runs. Body paragraphs in a
Subdoc therefore ignore the style the author applied to the placeholder line.

Proposal

Before patch_xml removes {{p var }} paragraphs, scan for style/alignment.
At render() time, apply those to plain body paragraphs of any Subdoc in the
context keyed by that variable name (Heading / List / Title / Subtitle left
unchanged). First occurrence wins.

Works for programmatic new_subdoc() and for Subdocs created by other means
(e.g. JSON CLI envelopes from a separate PR).

Implementation

• New docxtpl.p_style (scan_p_placeholder_styles, apply_p_placeholder_styles)
• Hooked at the start of DocxTemplate.render(), before build_xml / patch_xml
• Re-export scan_p_placeholder_styles from docxtpl

How to try

cd tests
python subdoc_p_style.py
