fix: suppress per-output compression INFO log spam with configurable log level

Root cause: _log_output_evaluation emitted INFO for every applied=True
outcome, flooding logs during long sessions with many tool outputs.

- Add per_output_evaluation_log_level config field (default: debug)
- Wire through CLI arg, env var, schema, and applicator
- failed_open outcomes always emit at INFO (safety signal preserved)
- Add 3 tests: debug default, info override, off suppression
- Fix all pyright warnings in touched files via typed casts
