fix(graphql): filter invalid schema queries from Sentry

[sentry]

This change modifies the GraphQL error formatter to prevent logging and capturing client-side schema validation errors (e.g., querying non-existent fields) in Sentry. Previously, anonymous external clients making such invalid queries would trigger Sentry events, creating unnecessary noise.

The error_formatter in apps/codecov-api/graphql_api/views.py now includes an explicit check for is_bad_query (indicating a schema validation error) and returns the masked error response without logging or capturing the exception in Sentry. The response to the client remains a generic INTERNAL SERVER ERROR to avoid leaking schema details.

Legal Boilerplate

Look, I get it. The entity doing business as "Codecov" is owned by Harness, Inc. In 2026 Harness acquired Codecov and as a result Harness is going to need some rights from me in order to utilize my contributions in this 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 Harness can use, modify, copy, and redistribute my contributions, under Harness's choice of terms.

Note

Low Risk
Observability-only change in error handling; no change to GraphQL responses or auth paths.

Overview
GraphQL invalid-field queries no longer hit Sentry or error logs.

The error_formatter in graphql_api/views.py already treats "Cannot query field" messages as client mistakes and masks them as a generic internal error for most callers. This PR adds an explicit elif is_bad_query branch so those cases skip log.error and capture_exception, which previously ran when the underlying error was not a known app exception type.

Client-facing behavior is unchanged: anonymous or masked responses still avoid leaking schema details.
