[MySQL] az mysql flexible-server mirroring enable/disable: Support Fabric Mirroring

[mohitsinha-ms]

Related command
az mysql flexible-server mirroring enable / az mysql flexible-server mirroring disable

Description
Adds CLI support for Microsoft Fabric Mirroring on Azure Database for MySQL Flexible Server via a new mirroring subgroup:

• az mysql flexible-server mirroring enable -g <rg> -n <server> --identity-resource-id <uami>
• az mysql flexible-server mirroring disable -g <rg> -n <server>

These wrap the fabricMirroringSettings/Default ARM resource (API version 2025-12-01-preview, added in Azure/azure-rest-api-specs#39083), an async PUT with state = Enabled|Disabled and a user-assigned managed identity.

This PR also bumps azure-mgmt-mysqlflexibleservers 1.1.0b2 → 1.1.0b3, the first SDK version exposing FabricMirroringSettingsOperations (begin_create_or_update, get, list_by_server); without it the command fails with AttributeError: 'MySQLManagementClient' object has no attribute 'fabric_mirroring_settings'. It also fixes the request-body construction in custom.py to match the 1.1.0b3 model (nested properties.state / properties.identityResourceId). Supersedes #32708.

Testing Guide
Prerequisites: register the preview feature (az feature register --namespace Microsoft.DBforMySQL --name enableFabricMirroring_public then az provider register --namespace Microsoft.DBforMySQL); a non-HA General Purpose MySQL 8.0 server with binlog_row_image=FULL (or NOBLOB), gtid_mode=OFF, aad_auth_only=OFF; and a user-assigned managed identity attached to the server.

# Enable Fabric Mirroring
az mysql flexible-server mirroring enable -g <rg> -n <server> \
  --identity-resource-id /subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<uami>
# -> returns the Default setting with "state": "Enabled", "provisioningState": "Succeeded"

# Disable Fabric Mirroring
az mysql flexible-server mirroring disable -g <rg> -n <server>
# -> returns "state": "Disabled", "provisioningState": "Succeeded"

Verified end-to-end against a live server (enable → Enabled, disable → Disabled). Automated scenario test added in test_mysql_scenario.py.
