Enhance Direct track text rendering with comprehensive layout preservation:
**Text Alignment (Task 5.3)**
- Add support for left/right/center/justify alignment from StyleInfo
- Calculate line position based on alignment setting
- Implement word spacing distribution for justify alignment
- Apply alignment per-line in _draw_text_element_direct
**Paragraph Formatting (Task 5.2)**
- Extract indentation from element metadata (indent, first_line_indent)
- Apply first line indent to first line, regular indent to subsequent lines
- Add paragraph spacing support (spacing_before, spacing_after)
- Respect available width after applying indentation
**Line Rendering Enhancements (Task 5.1)**
- Split text content on newlines for multi-line rendering
- Calculate line height as font_size * 1.2
- Position each line with proper vertical spacing
- Scale font dynamically to fit available width
**Implementation Details**
- Modified: backend/app/services/pdf_generator_service.py:1497-1629
- Enhanced _draw_text_element_direct with alignment logic
- Added justify mode with word-by-word positioning
- Integrated indentation and spacing from metadata
- Updated: openspec/changes/pdf-layout-restoration/tasks.md
- Marked Phase 3 tasks 5.1-5.3 as completed
**Technical Notes**
- Justify alignment only applies to non-final lines (last line left-aligned)
- Font scaling applies per-line if text exceeds available width
- Empty lines skipped but maintain line spacing
- Alignment extracted from StyleInfo.alignment attribute
