ReadOnly, ShowToolbar, ShowFormulaBar, ShowSheetTabs, and 15 Allow* parameters
gate workbook mutations and grey out the matching tools. Each ICommand declares
its SpreadsheetFeature so ExecuteAsync routes through one chokepoint.
Execute is now async (Task<bool>) so CommandExecuting handlers can await before
calling PreventDefault to veto a command. Tool bindings move from setter-style
dispatch to Value=/ValueChanged= async methods.
ChildContent replaces the built-in ribbon; the host cascades the active
Worksheet so tools in custom content don't need to track sheet-tab changes.
TableDesignTab is a new public component for the contextual tab.
Tests: 76 new (parameter rendering, ExecuteAsync gating per Allow* flag,
CommandExecuting + PreventDefault, ICommand.Feature mapping, ChildContent).
Also fixes two pre-existing SheetViewTests that hardcoded the old 24px row
default after it changed to 22px in 2e79dd7d.
