cleanup: remove /api/landclass handler + lib/landclass.py (extraction #4 shadow)

/api/landclass is edge-shadowed since extraction #4 — navi-landclass :8424
serves the route via nginx. Cleanup #4 removed the last in-process consumer
(netsyms_api._reverse_landclass), so lib/landclass.py is now fully orphaned.

- api.py: drop the @app.route('/api/landclass') handler + the
  `from .landclass import lookup_landclass, format_summary` import.
- DELETE lib/landclass.py (only consumer was the deleted handler).
- DELETE lib/landclass_test.py (SUT gone).

PADUS_DB_* vars in /opt/recon/.env are now dead in recon — flagged for an
out-of-band post-merge cleanup, not touched here (data, not code).
