Implement automatic dialog size detection

[Oleg-Melnik]

Summary

Implement content-driven dialog sizing that follows JDialog.pack()-style behavior while preserving explicit width and height overrides.

Fixes #118

Changes

• Default dialogs to automatic width and height detection and constrain fitted windows to their available bounds.
• Keep content and action buttons reachable through bounded, scrollable content after packing or resizing.
• Apply automatic sizing consistently to desktop, lightweight, built-in, and wizard dialogs.
• Add the reusable DialogHeading layout and configurable InputRow arrangement support.
• Add regression coverage for automatic and explicitly configured dialog dimensions.
• Bump Chords to 2.0.0-SNAPSHOT.95 and regenerate dependency reports.
