Changes to src/compile/mql_compiler.rs:
- Stage compilation to /tmp/mt5_compile_{ea}/ to avoid spaces in paths
(Wine /compile: chokes on spaces in paths like 'Application Support')
- Use bare /log flag - writes log adjacent to source instead of custom path
- Remove host_to_wine_path() conversion - use Unix paths directly
- Simplify MetaEditor invocation (no shell script on Linux)
- Clean up error handling logic
Fixes compilation failures when MT5 is installed in paths containing spaces.
