Add genlocke list and detail pages

Add GET /genlockes and GET /genlockes/{id} endpoints with aggregate
encounter/death stats per leg, and a frontend list page at /genlockes
plus a detail page at /genlockes/:genlockeId showing progress timeline,
cumulative stats, configuration, retired families, and quick actions.
Update nav link to point to the list page instead of /genlockes/new.
