fix: use bash array for docker args to preserve spaces in label/tag values

The flat string approach caused word splitting on label values that
contain spaces (e.g. description labels), which made docker interpret
split words as the PATH argument. Using a bash array with proper
quoting via "${args[@]}" prevents this.
