Research direction

Inspect the webpack configuration files and the current flat ESLint configuration. Cross-reference each eslint-env comment's environments and globals, remove only comments that are already represented elsewhere, and verify that the warnings no longer occur before the ESLint v10 upgrade.

Written by the indexing model from the issue text.

Description

Before upgrading to ESLint v10 there will be a few warnings to look into. Apparently eslint-env comments in the webpack configs are still considered part of the eslintrc (non-flat) era:

ESLintEnvWarning: /* eslint-env */ comments are no longer recognized when linting with flat config and will be reported as errors as of v10.0.0. Replace them with /* global */ comments or define globals in your config file. See https://eslint.org/docs/latest/use/configure/migration-guide#eslint-env-configuration-comments for details.

Quickly checking I think these are already correctly configured in the right places from when Alex migrated to the new config style, so it may just be as simple as removing these remnants — but I'll cross-reference the values and environments first, to check it's actually 1:1 mapped already, or there are deviations worth mentioning.
