Collaboration: Bump db_version to 61840 so upgrade_700() re-runs

The previous gate (< 61699) was below trunk's existing db_version
of 61833, which meant sites that had already run upgrade_700()
would not re-run it and the new collaboration table would never
be created via the upgrade path. Aligns the gate, version check,
and feature guard to 61840 with headroom for additional schema
changes this cycle.
