feat(logs): add auto-update toggle to Access Logs and Logs viewers

A checkbox in both the Xray Access Logs and panel Logs modals polls the
existing refresh every 5s while enabled, respecting the current row count,
level/filter, and Direct/Blocked/Proxy selections. The poller tears down on
close or untoggle. Adds a localized pages.index.autoUpdate key to all 13 locales.
