fix: pricelist selection preserved when opening configurations

- Remove 'auto (latest active)' option from pricelist dropdowns; new
  configs pre-select the first active pricelist instead
- Stop resetting stored pricelist_id to null when it is not in the
  active list (deactivated pricelists are shown as inactive options)
- RefreshPricesNoAuth now accepts an optional pricelist_id; uses the
  UI-selected pricelist, then the config's stored pricelist, then
  latest as a last-resort fallback — no longer silently overwrites
  the stored pricelist on every price refresh
- Same fix applied to RefreshPrices (with auth)
