Fix identity prompts to respect --interactive flag

[Copilot]

Identity selection prompts appeared even when --interactive=false was specified. The isInteractive() function in pkg/auth/manager.go checked TTY and CI status but not the flag itself.

Changes

• pkg/auth/manager.go: Modified isInteractive() to check viper.GetBool("interactive") before TTY/CI checks
• pkg/auth/interactive_test.go: Added test coverage for flag behavior

Implementation

func isInteractive() bool {
    // Check if interactive mode is enabled via flag or environment.
    if !viper.GetBool("interactive") {
        return false
    }
    
    // Check if stdin is a TTY and not in CI.
    return term.IsTTYSupportForStdin() && !telemetry.IsCI()
}

Now aligns with the existing pattern in pkg/flags/interactive.go.

Behavior

Command	Result (no default identity)
atmos list stacks --interactive=false	Error: "no default identity configured"
atmos list stacks (default)	Prompts user (if TTY)
ATMOS_INTERACTIVE=false atmos list stacks	Error

<issue_description>### Describe the Bug

When identities are present and no default is set.
Atmos will always prompt for identity.

Expected Behavior

If no default is set, and multiple identity are present, atmos should exit with an error code.

Steps to Reproduce

• Add 2+ identities to the atmos.yaml files (with no default value set)
• Execute atmos list stacks --interactive=false

Screenshots
