fix(import): refresh all providers immediately after SQL import

- Remove setTimeout delay that could be cancelled on component unmount
- Invalidate all providers cache (not just current app) since import affects all apps
- Call onImportSuccess before sync to ensure UI refresh even if sync fails
- Update i18n: "Data refreshed" (past tense, reflecting immediate action)
