On Cacti 1.2.31 with the Paper-plane theme, standalone editor dialogs have white backgrounds but inherit pale #ccc table text. Labels, checkboxes and help text are difficult to read, including in Map Style.

Add an escaped theme marker to the editor body and scope readable dialog/table/help colours to Paper-plane in the existing legacy stylesheet. Dark section headings retain their theme colours. The stylesheet remains restricted to Cacti releases earlier than 1.2.32; other themes and newer core theme handling are unchanged. Include an issue entry in the 2.0 changelog.

Validation:

• Reproduced and visually checked an isolated dialog using the installed Cacti 1.2.31 Paper-plane stylesheets: table text changes from #ccc to #333 on white, help text to #555, and section headings remain white on dark.
• Full PHP suite: 329 tests, 6,401 assertions passed, including curved-comment rendering/configuration tests.
• PHP syntax, manifest, translation-change and whitespace checks passed.

No live-server deployment is included in this PR.
