Initial Whisparr Cloudron app implementation

- Created Dockerfile with multi-stage build using thespad/whisparr image
- Added CloudronManifest.json with proper configuration (port 6969)
- Created start.sh script to launch Whisparr
- Added README.md with installation instructions
- Copied all required musl-compatible libraries:
  - musl libc dynamic linker
  - C++ standard library (libstdc++)
  - GCC support library (libgcc_s)
  - ICU libraries for .NET globalization
  - OpenSSL libraries for HTTPS/TLS
  - SQLite library for database operations
  - Brotli compression libraries
  - zlib library
- Configured for amd64 architecture (Cloudron compatible)
