feat(toolbars): support presets for selection and slash menus

[makhnatkin]

Shared configuration for all toolbars (Closes #1226)

• Added shared preset configuration for selection and slash toolbars.
• Deprecated legacy contextual configuration while preserving compatible fallbacks.
• Preserved command selection and updated open menus when configurations change.
• Updated customization examples, migration documentation, and regression coverage.

Summary by Sourcery

Configure selection and slash menus through shared toolbar presets while preserving legacy compatibility and reliable dynamic updates.

New Features:

• Add shared toolbar presets for configuring selection and slash toolbars alongside the main toolbars.
• Support slash-command aliases and contextual toolbar actions derived from shared preset items.

Bug Fixes:

• Update open contextual menus when toolbar presets change while preserving the selected command and editor history behavior.
• Hide contextual menus when configurations are empty, filtered out, unavailable, or otherwise produce no usable actions.

Enhancements:

• Retain legacy selection and slash configuration options as deprecated fallbacks while giving explicit contextual preset orders precedence.
• Keep contextual toolbars disabled on mobile and support dynamic preset changes without recreating the editor.

Documentation:

• Document shared configuration for all six toolbars and provide migration guidance from legacy contextual options.

Tests:

• Add unit and visual regression coverage for contextual presets, aliases, dynamic updates, fallbacks, conditions, mode switching, and mobile behavior.

Reviewer's Guide

This PR unifies selection and slash menus with the shared toolbar preset model, deriving contextual configurations from preset items and orders and propagating them through ProseMirror state so open menus update live. It retains legacy extension-option fallbacks, adds slash aliases and filtering behavior, updates built-in presets and documentation, and provides unit and visual regression coverage.
