Get-AzureBudgetAlertStatus

<#
.SYNOPSIS
    Reports budget configuration and current spend against thresholds.

.DESCRIPTION
    Lists every budget configured in the subscription with its amount,
    alert thresholds, and current spend, so budget alerts can be
    verified as actually configured and working rather than assumed to
    exist.

.EXAMPLE
    .\Get-AzureBudgetAlertStatus.ps1

.NOTES
    Requires the Az.CostManagement module and an active Connect-AzAccount session.
