Fouad Salkini b67915d9eb fix(combos): synchronize allowedProviders and allow invariant overrides on update (#13951)
* fix(combos): synchronize allowedProviders and allow invariant overrides

* docs: add PR reference to changelog fragment #13951

* fix(combos): only widen existing allowedProviders/allowedModelFamilies restrictions on edit

The dashboard's combo edit save unconditionally set overrideAllowedProviders
and unconditionally nulled allowedModelFamilies. When a combo had NO prior
allowedProviders restriction, the PUT route unioned the (empty) current
restriction with the new step providers, synthesizing a brand-new allowlist
out of nothing — the opposite of "no restriction" — so a later add-a-provider
update would start failing COMBO_008 where it previously succeeded.

- Gate the server-side union in PUT /api/combos/[id] so it only widens an
  ALREADY non-empty allowedProviders restriction; a combo with no restriction
  stays unrestricted.
- Only clear allowedModelFamilies when a new step's family actually falls
  outside the existing restriction, instead of always nulling it on any edit.
- Derive the provider id via resolveCanonicalProviderModel instead of a naive
  model.split('/')[0], so self-aliased no-auth providers (e.g. 'opencode' ->
  'opencode-zen') resolve to their real routing provider.
- Add a PUT-route-level regression test covering both the "no prior
  restriction stays unrestricted" and "prior restriction gets unioned" cases
  (the existing combo-update-invariants test only exercised
  combosDb.updateCombo() directly, bypassing this route branch).

* refactor(combos): extract computeAllowedRestrictionSync to keep handleSave under the complexity ratchet

The #13951 gating fix pushed handleSave's cyclomatic complexity past the frozen
new-code ceiling (16 > 15). Moving the allowedProviders/allowedModelFamilies sync
into a module-level helper restores complexityNewCode=0 with no behavior change.
