fix: add missing MCP error translation keys (RooCodeInc#6821)

* fix: add missing MCP error translation keys

- Added refresh_after_disable translation key
- Added refresh_after_enable translation key
- Added disconnect_servers_partial translation key
- Updated all 18 locale files with the missing keys
- Fixes the "errors.refresh_after_disable" display issue in MCP server management

* fix: remove fallback English strings from MCP error translations

As requested by @mrubens, removed the || operator and fallback English strings from:
- t("mcp:errors.disconnect_servers_partial")
- t("mcp:errors.refresh_after_disable")
- t("mcp:errors.refresh_after_enable")

The translation system will now rely solely on the localized strings without fallbacks.

* fix: translate MCP error messages to all locales

- Translated "refresh_after_disable" error message
- Translated "refresh_after_enable" error message
- Translated "disconnect_servers_partial" error message with count placeholder
- All 17 non-English locales now have proper translations instead of English text
