 87404f3702 refactor: move logging out of routes/shared.py into services/logging.py (#99) 
Create services/logging.py as the canonical home for setup_logging(),
all log format constants, named loggers, and _ml_logging_enabled.

Update all route modules and lab_api.py to import logging symbols from
services.logging and all other symbols from their canonical sources
(models.state, models.requests, models.responses, services.database,
services.deck_service, services.scryfall, services.import_helpers,
services.import_service, services.precon_service, services.forge_runner).

Delete routes/shared.py — the re-export hub is no longer needed.

Closes #61
