The DB-seeded Extension/ExtensionInstall catalog was dead weight:
nothing ever populated it on a real panel, so it fed Browse an empty
third lane redundant with the real sources (builtin folder scan, remote
registry, InstalledPlugin state), and its orphaned per-user config
plumbing connected to nothing a plugin could read (superseded by #49).
Removed: the two models, marketplace_service.py, all legacy /marketplace
CRUD/install/rate endpoints (the blueprint keeps only the registry
endpoints), the frontend published lane (catalog mappers, install/
uninstall handlers, rating stars, published stats) and its API methods.
Migration 046 drops the orphaned tables.
Pipeline + registry suites 29 green; lint 0 errors; build clean.
