fix(i18n): logical CSS direction utilities for RTL layout (#3541)

 - **fix(kiro): route enterprise IAM Identity Center accounts to their regional endpoint** ([#3631] — thanks @artickc): Kiro/CodeWhisperer access tokens and Q Developer profile ARNs are region-bound, so enterprise IAM Identity Center accounts outside `us-east-1` (e.g. `eu-central-1`) were rejected by the default host. Adds `resolveKiroRegion` (stored region → profileArn region → `us-east-1`) and `kiroRuntimeHost` (regional `q.{region}.amazonaws.com`, legacy `codewhisperer.us-east-1` for the default), routes chat + usage to the regional endpoint, and discovers the region-matched `profileArn` via `ListAvailableProfiles` in a best-effort `postExchange` hook. 9 tests.
 - **fix(combo): skip same-provider/connection targets on connection-level errors** ([#3637] — thanks @herjarsa): on connection-level upstream errors (408/500/502/503/504/524), remaining same-`provider:connection` targets in a combo request are now skipped to avoid hammering a known-bad connection, in both the priority and round-robin paths. Adjusted in review to **exclude OmniRoute circuit-breaker-open responses** (503 + `X-OmniRoute-Provider-Breaker` / `provider_circuit_open`) from this skip, preserving the invariant that a breaker-open is an ordinary target failure (the next same-provider target is still tried). Co-authored with @herjarsa.
 - **/v1/responses**: detect stream readiness for tool-call-only and `object`-less chunks so Codex-shaped (reasoning + tools) requests no longer fail with "Stream ended before producing useful content" (#3612)
+- **RTL locales (ar/fa/he/ur)**: use logical CSS direction utilities for the sidebar and key overlays so the layout mirrors correctly under `dir=rtl` (#3541, partial — core layout)
 - **Kiro/AWS auto-import**: set a descriptive account name and dedupe by `profileArn` so imports no longer create nameless duplicate "OAuth Account" rows (#3615)

+ * RTL layout regression test — #3541 (partial, core layout)
+ *
+ * For RTL locales (ar/fa/he/ur) the sidebar and key overlays must flip
+ * correctly when `dir=rtl` is set on <html>.  Tailwind v4 supports logical
+ * direction utilities natively (`start-*`, `end-*`, `ps-*`, `pe-*`, `ms-*`,
+ * `me-*`, `text-start`, `text-end`) which auto-mirror under dir=rtl without
+ * extra `rtl:` variants.
+ *
+ * This test reads the source files and asserts that the four high-impact
+ * components use logical classes instead of physical directional ones where
+ * those classes govern layout placement / offset.
+ *
+ * Runner: Vitest (included via `tests/unit/**\/*.test.tsx` in vitest.config.ts)
+ * Command: npm run test:vitest -- --reporter=verbose --testPathPattern=rtl-logical
