Move model routing management into Settings and add a unified
model alias editor for exact and wildcard remaps.
Sync combo defaults with global routing strategy settings, add
localized combo onboarding copy, and expand routing i18n across
supported locales.
Also fix supporting routing behavior by accepting all strategy
values in settings schemas, preserving connection ids in combo
tests, honoring non-stream JSON requests for CC-compatible
providers, and handling hashed external package subpaths.
