Remove the Export SCV option from Save Template screen

The Export SCV option on the Save Template screen exports the SCV configuration directly from the SCV database using the format for SCV-specific templates. This functionality was used when SCV templates were separate from SCP templates; it was however temporarily maintained to support upgrades. Currently, it is not possible to load SCV-specific templates. Hence with this change, the export option is also removed.

With this change, the SCV-specific templates are completely removed from SCP. All SCV configuration is now loaded/exported using the standard SCP template format.

Action required: The "Export SCV" option is removed upon upgrade; hence no immediate action is required. SCV configuration is included in standard export options in Save Template.
