Component.show() updateDepth fix

Changed src/component/Base.mjs show() method to set updateDepth to -1 instead of 2.

Rationale: When re-showing bigger component trees, we need to ensure the full tree is updated, not just 1 child level. This was causing buggy behavior in the Colors app and the new AgentOS app, particularly when closing popup windows to re-integrate widgets.

Change:

// src/component/Base.mjs
show() {
    // ...
    if (me.parentId !== 'document.body') {
        me.parent.updateDepth = -1; // Changed from 2
        me.parent.update()
    }
    // ...
}
