protondrive: fix segfault when copying files missing revision metadata

Browse Source 
When a Proton Drive file has no active revision attributes,
readMetaDataForLink returns a nil FileSystemAttrs and Object.originalSize
is left as nil. Object.Open then dereferenced this nil pointer when
calling fs.FixRangeOption, causing a SIGSEGV during copy.

Use Object.Size() instead, which already implements the correct fallback
to the link size when originalSize is unavailable.

This updates the github.com/rclone/Proton-API-Bridge package to fix a
segfault when reading files with no metadata.

Fixes #9377
Fixes #9117
