fix(sdk): require at least one FQN in ForAttributeValues

[marythought]

Summary

• Add panic guard for zero-argument calls to ForAttributeValues
• Aligns with Java SDK's IllegalArgumentException guard and the proto's fqns.size() > 0 constraint
• Follow-up to feat(sdk): add ergonomic Resource constructors for authorization #3337

Test plan

• TestForAttributeValues_ZeroArgs_Panics verifies the panic
• All existing tests pass (15/15)
• golangci-lint clean
• CI checks pass
