UnitPickList.GetVariantCriteria put the value of a "customerid:<value>"
variant from the request into the query unparsed, reachable by any login
(security review F43, found during case 4712). The value is now parsed as a
long; anything else means no restriction, as 0 already did. The client's
format ("customerid: 5") still works.
Checked: new test fails on the old code, passes now; pick-list tests 10/10.

PickListSqlBuilder put the search text and the tag search text into the SQL
inside quotes with no escaping, reachable by any login (security review F18);
an apostrophe in a search also made the query fail. The builder now writes
@plq / @pltag and PickListFetcher adds them as Npgsql parameters (same %text%
match; wildcards typed by the user still apply).
Changelog: searching selection lists for text with an apostrophe now works.
