people me/whoami fails when OAuth client project lacks People API

[cct08311github]

Repro on gog v0.11.0 with a valid OAuth account:

• gog drive ls succeeds
• gog gmail search succeeds
• gog calendar calendars succeeds
• gog me and gog whoami fail with: Google API error (403 accessNotConfigured): People API has not been used in project ... before or it is disabled.

This makes profile discovery depend on the OAuth client project having People API enabled even when the account is otherwise authenticated and other services work.

A safer behavior would be to fall back to token/id-token identity claims or degrade gracefully instead of failing hard.
