fix(i18n): add missing sidebar message keys to all locales (#896)

The sidebar `messages` namespace was missing six keys that are referenced
in `useSidebarController.ts`:

- messages.updateProjectError (rename / star-toggle failure)
- messages.refreshError (project list refresh failure)
- messages.restoreProjectFailed / restoreProjectError
- messages.restoreSessionFailed / restoreSessionError

`updateProjectError` and `refreshError` are called via `t()` without an
inline default, so on failure users see the raw key string
"messages.updateProjectError" / "messages.refreshError" instead of a
message. The four restore.* keys have inline English defaults in the code,
so they previously fell back to English even in non-English UIs.

Adds all six keys to every locale (de, en, fr, it, ja, ko, ru, tr,
zh-CN, zh-TW), matching the existing wording/style of the neighbouring
delete/create messages in each file.
