fix: resolve Chinese filename garbling on upload and page update failure (#72, #71)

- Fix multipart upload parsing to use Buffer operations instead of latin1
  string conversion, preserving multi-byte characters in filenames (#72)
- Support RFC 5987 filename* encoding for cross-platform compatibility
- Fix in-page update by running npm install directly instead of CLI command
  that kills the server process before response is sent (#71)
- Add no-cache header to version check to avoid stale latest version
- Change version check interval from 4 hours to 1 hour

Closes #72, Closes #71
