[Enhancement] Enhance region selection for Azure instance creation

Descrition

Currently, creating an Azure instance using mapt 0.8.0 may fail if the selected region does not support the required resource type.

Suggested Enhancement:

If the requested region does not support the resource type, mapt should automatically select an alternative from the list of available regions rather than failing

Logs:

error: Status=400 Code="LocationNotAvailableForResourceType" Message="The provided location 'southafricawest' is not available for resource type 'Microsoft.Storage/storageAccounts'. List of available regions for the resource type is 'eastus,eastus2,westus,westeurope,eastasia,southeastasia,japaneast,japanwest,northcentralus,southcentralus,centralus,northeurope,brazilsouth,australiaeast,australiasoutheast,southindia,centralindia,westindia,canadaeast,canadacentral,westus2,westcentralus,uksouth,ukwest,koreacentral,koreasouth,francecentral,australiacentral,southafricanorth,uaenorth,switzerlandnorth,germanywestcentral,norwayeast,westus3,jioindiawest,swedencentral,qatarcentral,polandcentral,italynorth,israelcentral,mexicocentral,spaincentral,newzealandnorth,indonesiacentral'."

Start by reproducing the Azure instance creation failure from the linked workflow run and trace the region-selection path that handles the LocationNotAvailableForResourceType error. Done means an unsupported requested region results in selection of an available alternative instead of creation failing; the payload names no source files or tests.
