Fix menu bar icon reverting to default for CLI-authenticated users

[nfarina]

Description

Claude Usage was successfully fetching my data and showing it in the popup, but the icon would periodically revert to default.

Changes

Align menu bar rendering with the existing Claude fetch auth fallback. The app could successfully fetch usage via system Keychain CLI credentials from claude login, but some UI paths still treated the profile as unauthenticated and repainted the default icon. This updates the single-profile menu bar/config checks to use the same “any available credentials” logic as the fetch path, so custom icon styles like “icon with bar” persist correctly.

Screenshots / Screen Recordings

Example of the problem:

Checklist

• I have tested these changes on a running build
• I have attached screenshots/recordings for any visual changes
• I have not introduced App Group or grouped Keychain usage
• I have added localization keys for any new user-facing strings
