* fix(control-ui): keep the dashboard mounted with a reconnect banner on gateway drops
Once a session is established, a dropped gateway WebSocket no longer
unmounts the dashboard into the login gate. The client's close handler
now reports willRetry (the same fact that drives its reconnect
scheduling), the gateway store derives a `reconnecting` snapshot state
from it (everConnected && willRetry), and the app shell stays mounted
with an amber "Gateway connection lost - reconnecting" banner plus a
Retry now action while the client retries with backoff. The login gate
is reserved for first connects, credential rejections, and manual gate
submissions; event-gap recovery also no longer flashes the gate.
createApplicationGateway moved from bootstrap.ts to gateway-store.ts
with an injectable client factory for direct behavior tests. Adds the
previously unstyled `.callout.warn` variant and a "Connection loss and
reconnect" docs section.
Fixes#100475
* chore(i18n): regenerate control-ui locale bundles for connection banner strings
* chore(control-ui): unbreak CI - add reconnecting to overlays snapshot fixture, regenerate docs map
* chore(i18n): re-sync locale metadata after rebase onto refreshed main locales
* chore(i18n): refresh raw-copy baseline after rebase
