Add Select Subscriptions button to Resources view toolbar

[alexweininger]

I've always wondering if this would provide a better UX. I've added the Select Subscriptions button to the title bar for the Azure Resources tree view.

What do we think? In my opinion this doesn't hurt anything, and can only help users who would potentially not see the button on the subscription items.

Pull request overview

This PR improves discoverability of the existing Select Subscriptions command by adding it to the Azure Resources view title toolbar, placing it between the existing Group By submenu and Refresh actions.

Changes:

• Added a menus.view/title contribution for azureResourceGroups.selectSubscriptions scoped to view == azureResourceGroups at navigation@3.
• Shifted the existing refresh titlebar commands (azureFocusView.refreshTree, azureResourceGroups.refreshTree) from navigation@3 to navigation@4 to preserve the intended ordering.

Realized we probably need to hide this button in states where there's no subscriptions in the tree yet, @copilot can you look into that? What if the user isn't signed in yet, does the command handle it fine? Should we hide the button in some cases?

The command already handles the "not signed in" case gracefully — it catches isNotSignedInError and shows an info message with a "Sign In" button. That said, it's better UX to hide the toolbar button when there are no subscriptions in the tree yet.

I've added a new context key azureResourceGroups.isSignedIn (commit Hide Select Subscriptions toolbar button when not signed in):

• Set to true after subscriptions are successfully loaded (regardless of count — even "all filtered out" still shows the button so the user can change their filter)
• Set to false when isNotSignedInError is caught

The toolbar button's when clause now includes && azureResourceGroups.isSignedIn, so it's hidden when the user isn't signed in and during initial load (key is undefined = falsy), and appears once the user is authenticated.

@copilot what do we do for the other buttons on the ribbon, we should just handle this button the same as those. I think it's fine to keep it visible if the user isn't signed in yet if that's what we do for the other buttons and since the command handles the not signed in error gracefully.

Reverted — the button now uses the same when: "view == azureResourceGroups" condition as the other toolbar buttons, with no sign-in gating.
