Use SB.delay for editor initialization like Chili does

Found the correct mechanism! Chili uses SB.delay() in main_window_panel.lua
to defer editor creation until after SB.view is assigned.

SB.delay(func) defers execution until the next GameFrame, ensuring:
1. View() constructor completes
2. SB.view = View() is assigned in widget.lua
3. THEN editors are created (can safely access SB.view)

Changes:
- Added PreCreateAllEditors() that uses SB.delay() for all editors
- Called from InitializeRmlUi() to match Chili's upfront initialization
- Removes lazy creation in OpenEditor() - editors should already exist
- Catches errors early while avoiding SB.view nil issues

This is the proper architecture, matching the original Chili approach.
