fix(windows): normalize Windows file paths with leading slash and add i18n to link safety dialog

Strip spurious leading slash from Windows drive-letter paths (/D:/foo → D:/foo) in parseLocalFileTarget so that workspace-relative comparison succeeds and local files can be opened correctly. Display the normalized path in the confirmation dialog. Internationalize all link safety dialog and toast strings across 10 locales.
