                                <#

.SYNOPSIS

    Generates an interactive HTML dashboard report for GCP environments.

.DESCRIPTION

    Orchestration script that authenticates to GCP (via service account key or

    existing gcloud session), scans a project for Compute Engine VMs, Cloud SQL

    instances, and forwarding rules, and produces a searchable, sortable Bootstrap

    Table HTML dashboard. Output includes both a JSON data file and a self-contained

    HTML report.

.PARAMETER KeyFilePath

    Path to a GCP service account JSON key file for authentication. If omitted,

    uses the existing gcloud CLI session.

.PARAMETER Project

    The GCP project ID to scan. If omitted, prompts interactively.

.PARAMETER SkipCloudSQL

    Exclude Cloud SQL instances from the dashboard results.

.PARAMETER SkipForwardingRules

    Exclude forwarding rules (load balancers) from the dashboard results.

.EXAMPLE

    .\Get-GCPDashboard.ps1 -Project "my-gcp-project"

    Generates a dashboard using the default gcloud session for a specific project.

.EXAMPLE

    .\Get-GCPDashboard.ps1 -KeyFilePath "C:\keys\sa.json" -Project "my-project"

    Authenticates with a service account and generates the dashboard.

.EXAMPLE

    .\Get-GCPDashboard.ps1 -Project "my-project" -SkipCloudSQL -SkipForwardingRules

    Generates a dashboard with only Compute Engine instances.

.EXAMPLE

    .\Get-GCPDashboard.ps1 -Project "prod-project"

    Scans all Compute, Cloud SQL, and Forwarding Rule resources in the production project.

.OUTPUTS

    System.Void

    Produces a JSON file (gcp_dashboard.json) and an HTML dashboard

    (GCP-Dashboard.html) in the system temp directory, then opens the HTML in the default browser.
