PMM-13967 Add support for ClickHouse and VM URLs in dump service (#3978)

* PMM-13967 Add support for ClickHouse and VM URLs in dump service

Enhanced the dump service to accept ClickHouse and VictoriaMetrics URLs. Updated the constructor and related logic to utilize these URLs for exports. Modified initialization in main.go to provide the required URL values.

* PMM-13967: Add URLs struct documentation comment

Added a comment to document the purpose of the URLs struct in dump.go. This improves code clarity and helps developers understand its usage.

* PMM-13967 Update flag name for VictoriaMetrics URL in dump service

Renamed the CLI flag from "--vm-url" to "--victoria-metrics-url" to improve clarity and alignment with naming conventions. This change ensures flag names are more descriptive and consistent.
