fix: resolve test failures across ResourceDocs, AbacRules, and v7→v6 bridge

- JSONFactory1_4_0: add specifiedUrl to resource-doc cache key so v7.0.0
  requests don't serve cached v6.0.0 specifiedUrl values (fixes
  V7ResourceDocsAggregationTest property 2.10)
- Http4s700: add v700→v600 bridge (HttpRoutes rewrite) so unhandled v7.0.0
  paths delegate to Http4s600 instead of falling through to Lift, which has
  no v6 routes (fixes Http4sServerIntegrationTest)
- Http4s600: rename bridge v600→v500 (skip v5.1.0 whose own bridge is
  disabled); wire wrappedRoutesV600Services to use it
- AbacRuleTests: pre-create 4 users in beforeAll so the statistical
  permissiveness check has a >1 user sample and doesn't falsely reject rules
- ResourceDocsTest: accept either liftweb or http4s technology value since
  the first resource doc is non-deterministic in a mixed migration state
