Fix mount properties not being passed to PHP worker spawner in v2 worker

The blueprints v2 worker was not correctly passing mount configurations to
the PHP CLI worker spawner. RunCLIArgs uses hyphenated property names like
'mount-before-install' and 'mount', while WorkerBootRequestHandlerOptions
expects camelCase 'mountsBeforeWpInstall' and 'mountsAfterWpInstall'.

Without this mapping, spawned PHP CLI workers would not have access to
/tmp and other mounted directories, causing 'Could not open input file'
errors when running blueprints that spawn PHP subprocesses.
