refactor(storageCleaner): simplify architecture and improve type semantics

- Remove RELOAD_TAB message chain, use chrome.tabs.reload() directly
- Rename IndexedDB label to '站点存储' for accuracy
- Introduce StorageSizeInfo type to distinguish bytes vs count
- Rename totalSize to totalBytes for clarity
- Merge runCleanScript into runScript to reduce duplication
- Rename CleaningResult.success to overallSuccess to avoid confusion
- Remove unused domain state and setDomain call
