fix(registry): all 5 CucumberIT suites green — device nav + iotReady filter

Three root causes fixed:

1. DeviceCucumberIT — duplicate step class removed from bdd.device; moved
   to dedicated devicebdd package with its own TestSetup and glue scanning,
   preventing duplicate-step conflicts with IoT suites.

2. DeviceNavigationSteps — ?-in-Cucumber-expression treated as optional-char
   quantifier. Changed GET /devices?capability=, ?deviceClass=, ?protocol=
   patterns to anchored regex (^…$) with (.+) capture so literal ? matches.

3. IotProfileCucumberIT iotReady=true — CanonicalQueryFilter was silently
   redirecting ?iotReady=true to the canonical URL (which omitted iotReady).
   RestAssured followed the 302 and the server never saw the parameter.
   Fix: add iotReady to QueryNormalisationService.canonicalForReplacements
   with normaliseIotReady ("true" → "true", else absent).
   ServiceResource now reads iotReady via UriInfo (bypasses JAX-RS @QueryParam
   which is downstream of the filter rewrite). RegistryService uses primitive
   boolean + INNER JOIN iot_profiles when iotReady=true.
