data_table v1.3.1: Dots renderer via ImDrawList (font-independent) + recompile all apps with fn_table_viz (issue 0081-O.6)

- Replace TextColored+glyph with ImDrawList::AddCircleFilled in CellRenderer::Dots.
  Dots are now font-independent: no dependency on Unicode glyph coverage. Fixes
  "dots show as ?" on Karla/Roboto/Inter fonts that lack Geometric Shapes block.
- dots_glyph_size now controls circle radius (px) instead of font scale.
- BadgeRule.label is ignored for Dots (documented in data_table_types.h + docs).
- data_table.md bumped to v1.3.1 with capability growth log entry.
- docs/capabilities/data_table_renderers.md: Dots section updated + Common pitfalls
  entry added: "Asumir que cualquier glyph Unicode renderea".
- dag_engine_ui/tabs.cpp: removed stale "● glyph" comment from BadgeRule.
- Recompiled: dag_engine_ui, registry_dashboard, graph_explorer, navegator_dashboard,
  odr_console. All 5 apps deployed to Desktop/apps/. Build Linux + tests 4/4 green.
