fix(sidebar): extend faded labels until row actions appear

[waleedlatif1]

Summary

• Let faded sidebar labels use the idle action space, revealing options on hover, keyboard focus, or while their menu is open.
• Apply the same behavior to workspace and organization sidebars, collapsed menus, the workspace switcher, and editor chat history. Preserve status indicators and visible actions on touch devices.
• Keep menu widths stable and make inline dropdown actions keyboard-accessible without selecting the row.

Type of Change

• Bug fix

Testing

Tested the running app with long labels, hover, keyboard focus, folder options, open menus, and collapsed navigation. Checked no-hover layouts in a component preview. All 145 focused tests, app type-check, lint, 46 repository audits (including API boundary validation), and generated-file checks pass.

Summary

This PR centralizes sidebar row-action reveal behavior and extends the EMCN dropdown-menu item API for stable labels and keyboard-accessible inline actions.

• Adds a shared SidebarRowActions component for hover, focus, open-menu, and touch states.
• Applies consistent action and indicator handling across workspace, organization, chat, workflow, and folder rows.
• Adds keyboard focus transitions and responsive action-space reservation to dropdown-menu items.
• Migrates editor chat history to the shared dropdown action pattern and adds focused behavioral tests.
