Force report processing does not reprocess reports already marked as processed

[sr-rossanderson]

Patchman supports forcing report processing, but the force behaviour is not propagated through to Report.process().

A processed report can be selected for reprocessing by the CLI, but Report.process() immediately exits because it checks:

if self.processed:
    return

Expected behaviour:

When force=True, already-processed reports should be processed again.

Suggested fix:

def process(self, find_updates=True, verbose=False, force=False):

and:

if self.processed and not force:
    return

Then pass the CLI force value through:

report.process(find_updates=False, force=force)

Impact:

Repository mapping changes and similar processing fixes cannot be applied retroactively without directly modifying report state or database records.
