fix(editor): remove the redundant top-bar settings button

The gear icon between the theme toggle and Export opened the shortcuts
configuration dialog — the same dialog already reachable as "Keyboard
Shortcuts" from the OpenScreen wordmark menu. Unlike AI settings, which
llm-providers.md documents as an intentional "two doors, one dialog",
this second door was just a leftover.

Removed the button and its icon import, the now-dead `topbar.settings`
string from all 13 locales, and the two manual e2e checklist lines that
tested or referenced the removed control.
