* refactor(ui): move dreams page modules to agents/memory (verbatim)
* refactor(ui): sidebar IA cleanup: Activity to Settings, Dreams into Agents Memory tab, single MCP mutation owner, Usage icon
Folds the per-agent Dreams page into the Agents page as a Memory panel and
deletes the dreams route; moves the session-scoped Activity page out of the
sidebar into Settings > System next to Logs; removes the MCP enable/disable
toggle from Settings > MCP so the Plugins page is the single mutation surface
for config.mcp.servers; gives Usage a coins icon so it no longer collides
with Overview.
Closes#104590
* docs: update Control UI docs for Activity/Memory/MCP sidebar changes
* fix(scripts): fail control-ui i18n sync closed on new untranslated keys without provider auth
An unauthenticated ui:i18n:sync silently recorded English fallbacks, which the
shipped-fallback CI gate then rejects; post-merge translation is owned by the
control-ui-locale-refresh workflow. Sync now errors on new untranslated keys
without a provider (OPENCLAW_CONTROL_UI_I18N_AUTH_OPTIONAL=1 opts back in),
and the ui AGENTS guide documents the commit-en.ts-only contributor flow.
* chore(ui): translate new sidebar keys, refresh i18n baseline, localize Memory tab expectation
