fix(text): integrate ignored fields across text-bearing entities

- MultiLeader: stop double-scaling when ctx.text_height (WCS-baked) is set;
  use it as-is and only multiply by scale_factor + anno on the fallback path.
  ctx.text_width gets the same treatment.
- Text / Attribute: width_factor and oblique_angle are entity-authoritative.
  The previous entity*style multiplication / addition mis-rendered any text
  whose TXSTYLE had a non-default width_factor or oblique_angle (RR 0.6,
  STYLE2 15°, Romans/ARIEL/A32 0.65-0.8 in the sample file).
- MText: honour TXSTYLE is_backward (negative width_factor mirror) and
  is_upside_down (180° rotation). measure_mtext_chars uses positive
  magnitude so anchor math stays correct under backward text.
- Tolerance: use tol.dimension_gap when set instead of the hard-coded
  0.35 * height heuristic.
- Table: cell text height / font / alignment resolve through
  CellContent -> CellStyle -> TableStyle.{title|header|data}_row_style
  -> compiled-in defaults. Row classification respects the suppressed
  flags. Cell + content rotation applied.
