Draft: remove query_builder from mypy typing-issues list

[cursor]

Summary

• Remove sentry.snuba.metrics.query_builder from the tool.mypy.overrides "sentry modules with typing issues" list in pyproject.toml.
• Fix all newly-exposed mypy errors in src/sentry/snuba/metrics/query_builder.py by tightening/aligning type annotations and narrowing logic around metric/groupby/orderby handling.
• Keep behavior the same while making type expectations explicit (operation typing, param casting, metric field assertions, discover interval validation, and component-entity mapping typing).

Validation

• ✅ .venv/bin/python -m mypy src/sentry/snuba/metrics/query_builder.py
• ✅ .venv/bin/prek run -q
• ⚠️ make test-selective could not run in this environment because gcloud is not installed.
• ⚠️ SENTRY_SKIP_SERVICE_VALIDATION=1 .venv/bin/pytest -n3 -svv --reuse-db tests/sentry/snuba/metrics/test_query_builder.py fails due missing local Redis (ConnectionRefusedError: localhost:6379).

@armenzg could you please review this draft PR?

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
