fix(KFLUXINFRA-2440): Resolve API timeout when listing high-volume resources (#9430)

Backups were failing with timeout errors when
listing >57k Konflux snapshots.

This commit updates the Velero arguments in
`DataProtectionApplication`:

- Set `client-page-size` to 500 to prevent API
  server timeouts by chunking requests.

- Set `client-qps` to 50.0 and `client-burst` to
  100 to maintain backup speed with pagination
  enabled.

While this is was observed in `stone-prd-rh01`,
patch `stone-stg-rh01` first to ensure the the fix
does not cause any issues or regression.
