Adds PUT /versions/:id/baseline/:logid that, in one transaction, drops
the segment's rows and log entry and replays the baseline or reference
SQL with new params. The endpoint refuses (409) if any scale, recode,
or clone has been applied — those operations were calibrated against
the old totals and would silently misreconcile.
Baseline view gets an Edit button on each segment (hidden once
forecast operations exist), populating the form with the original
filters, offset, and note. Submit issues PUT in edit mode, POST
otherwise. POST baseline and POST reference now also persist the
structured filters in pf.log.params so edit can reload them.
