feat(resource-value-verification): add apiserver resval trace log (task 4.2)

Browse source 
One logger.Debug("resource-location stored", ...) call in
OnResourceLocationUpdated, immediately after store.ResourceLocations.Put,
logging resource/host/value as zap fields. Debug-level only, matches this
package's existing logging convention (reuses convert.go's field names).

Live-confirmed against a real deployment with logging.level: debug.

Also surfaced (but did not fix, out of boundary - pure Go change, no
possible causal link) a pre-existing xce_test segfault on string-typed
resupdate (type/model) - uninitialized stack memory, non-deterministic,
invisible to ASan. Logged as bug-1574; flagged in tasks.md as a risk for
task 7.1's default resource set and task 8.1's live e2e run.
