feat(web): add workspace sharing management i18n and update share modal

- Add new i18n keys for share management UI (shareSpace, shareSpaceTitle, shareSpaceNote) in both English and Chinese translations
- Update ShareModal title to use new 'shareSpace' i18n key for better UX clarity
- Update ShareModal description and note text to use new i18n keys (shareSpaceTitle, shareSpaceNote)
- Fix parser_config field name from 'third_party_platform' to '_third_party_platform' in CreateModal for proper form binding
- Improve share modal messaging to better communicate workspace sharing status and access control
