refactor(stats): restructured embedded client archive

- Migrated embedded client archive from base64 constant to lazy-loaded text file for reduced bundle size.
- Refactored extractEmbeddedClientArchive() to accept archiveBytes parameter, decoupling archive loading from extraction logic.
- Optimized getLatestMtime() to use parallel Promise.allSettled() instead of sequential awaits for improved performance.
- Replaced Buffer.from().toString('base64') with btoa() for base64 encoding in clipboard module.
