fix: correct syntax errors in auth_test.go

[Copilot]

Two syntax errors in internal/api/auth_test.go were causing linter failures:

• Line 51: Stray closing parenthesis after mockTokenCredential.GetToken() method
• Line 732: Missing closing brace for TestUnit_NewAuthBase_InitializesCliTokenCache() function

Both errors prevented the file from compiling and blocked all typecheck validation.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• login.microsoftonline.com
  • Triggering command: /tmp/go-build3879096377/b001/api.test /tmp/go-build3879096377/b001/api.test -test.testlogfile=/tmp/go-build3879096377/b001/testlog.txt -test.paniconexit0 -test.timeout=10m0s -test.run=TestUnit -test.v=true ider-power-platf-ifaceassert ux-amd64/pkg/tool/linux_amd64/compile (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
