chore: cleanup docs, add bilingual READMEs, fix binary path resolution and UI layout

- Remove outdated docs/ files and generated reports
- Add resolveBinaryPath helper for robust MySQL binary discovery
- Widen MySQL config textarea to half-width in cluster deploy form
- Add Chinese and English README files
