Alejandro García MontoroandMattermost Build ecd72f79bd MM-68787: Support sovereign-cloud endpoints for Azure Blob Storage (#36732)
* Support sovereign-cloud endpoints in the Azure Blob Storage backend

Adds an AzureCloud enum to FileBackendSettings and the matching
FileSettings / ExportFileSettings entries, defaulting to commercial.
The supported values pick the service URL the SDK signs against:

  - commercial: vhost-style against blob.core.windows.net, exactly
    the existing default. Only the storage account name is needed.
  - government: vhost-style against blob.core.usgovcloudapi.net, no
    user-supplied endpoint. Only the storage account name is needed.
  - custom: the admin-provided AzureEndpoint is the full service URL,
    scheme and storage account included, and Mattermost passes it to
    the SDK unchanged. Covers Azurite, reverse proxies, Azure China,
    and any future Azure cloud Mattermost has not codified a preset
    for.

Wires the new field through NewFileBackendSettingsFromConfig,
NewExportFileBackendSettingsFromConfig, ConfigToFileBackendSettings,
SetDefaults, the System Console (File Storage and Export Storage
panels) with matching i18n strings, and a dedicated Cypress spec.
Azurite test settings switch to AzureCloud=custom with the full
http://host:port/account/ URL so the existing integration suites
keep driving Azurite without any conditional URL plumbing inside the
driver. buildAzureServiceURL is now total: it returns an error for
custom-without-endpoint and for unknown enum values rather than
producing a malformed URL.

* Hide S3 File Storage fields when a different driver is selected

Match the existing Azure-field behavior: when the selected file storage
driver is not Amazon S3, hide the S3-only fields entirely instead of
just disabling them. Both driver groups already use this hide-when-
inactive pattern in the dedicated export storage section.

The Cypress assertion in azure_blob_storage_spec.js that codified the
old disable-only behavior is updated to expect not.exist.

* Address review feedback on AzureCloud validation and config-test endpoints

- Switch FileSettings.isValid AzureCloud / ExportAzureCloud value
  checks from slices.Contains to a switch statement, matching the
  closed-enum style used a few lines above for DriverName.
- Revert the io.EOF suppression in testFileStore and testEmail. The
  suppression was bot-suggested log-noise polish; reviewer prefers
  to keep the original error handling for those endpoints.
- Drop the redundant "http(s)" qualifier from the scheme check comment
  in buildAzureServiceURL.
