fix(providers): add claude-sonnet-5 to Kiro model catalog (port from 9router#2267)

The Kiro provider's model catalog (open-sse/config/providers/registry/kiro/index.ts
models[]) was missing claude-sonnet-5, so the model could not be selected or routed
on the Kiro provider even on accounts that already had access to it — surfacing as
"claude-sonnet-5 is not supported". The registry models[] is both the model selector's
source and the fallback for the live CodeWhisperer ListAvailableModels fetch, so the
gap made the model invisible end-to-end. Added the single entry (1M context / 128K
output, mirroring the existing Claude entries).

 ### 🔧 Bug Fixes
 
+- **providers (Kiro — Claude Sonnet 5):** the Kiro provider's model catalog was missing `claude-sonnet-5`, so the model could not be selected or routed even on accounts that already had access to it ("claude-sonnet-5 is not supported"). Added the model to the Kiro registry (`open-sse/config/providers/registry/kiro/index.ts`) as a 1M-context / 128K-output Claude model, mirroring the existing Claude entries; the registry `models[]` feeds both the model selector and the live CodeWhisperer `ListAvailableModels` fallback, so the model is now selectable and routable. Regression guard: `tests/unit/kiro-claude-sonnet-5-2267.test.ts`. (thanks [@openbioinfo](https://github.com/openbioinfo))
+
 - **settings (model aliases — self-heal after restart):** the Settings → Routing page showed "No exact-match aliases configured" after a server restart even though the aliases were persisted in the DB. Aliases are held in a module-local `_customAliases` map in `modelDeprecation.ts` that the boot path hydrates, but Next.js compiles the app-route module graph separately from the startup graph (the same webpack chunk-splitting class as #5312), so the `GET /api/settings/model-aliases` handler read a different, un-hydrated copy. The handler now self-heals: when its in-memory alias map is empty it reads `settings.modelAliases` from the DB (via the existing `getSettings()` db module — no raw SQL in the route) and repopulates the map, so the UI reflects the persisted aliases on the first GET after a restart. Regression guard: `tests/unit/model-aliases-settings-route-selfheal.test.ts`. ([#5777](https://github.com/diegosouzapw/OmniRoute/pull/5777) — thanks [@jleonar2](https://github.com/jleonar2))
 
 - **providers (grok-cli token auto-refresh):** grok-cli OAuth tokens were never proactively refreshed before their real expiry. `mapTokens` hardcoded `expiresIn: 21600` (6 h) regardless of the token's actual lifetime, so the persisted `expiresAt` was always "now + 6 h" and the proactive `tokenHealthCheck` sweep (refresh when `expiresAt - now < 5 min`) fired 6 h after import instead of shortly before the token really expired. `mapTokens` now computes `expiresIn` from the authoritative `expires_at` field in `~/.grok/auth.json` (ISO → epoch-seconds) with a fallback to the JWT `exp` claim (payload-only decode, no signature trust); the hardcoded `21600` is kept only when neither is present. Regression guards: 3 new cases in `tests/unit/grok-cli-oauth.test.ts` (JWT `exp`, JSON `expires_at`, and the fallback). ([#5775](https://github.com/diegosouzapw/OmniRoute/pull/5775) — thanks [@Chewji9875](https://github.com/Chewji9875))
