fix(test): correct test expectations and logic

Httptest and similar callers often leave Host unset; fall back to URL
for scheme, host, port, and addr substitution.

jsonstore drops the IsTest load short-circuit and duplicate loadNS map
registration; tests isolate storesPath. Skip MaxMind background updates
when IsTest. Tests restore APISkipOriginCheck, use app-scoped OIDC
state cookies, attach route context in middleware helpers, and use
locked buffers for concurrent log capture.
