Paco Cartones 20af3988cf fix(a2a): use a constant-time bearer compare in /api/a2a/tasks (#10544)
* fix(a2a): use a constant-time bearer compare in /api/a2a/tasks

* fix(a2a): drop new Function from tasks-auth test in favor of dynamic import

The regression test for the constant-time bearer compare loaded tokensMatch
and authenticateA2A by regex-extracting their source and eval'ing it via
new Function, which trips the repo's no-new-func/no-implied-eval ESLint
rules (error-level everywhere, including tests). Export both helpers as a
test seam from the route module (mirrors the existing
bridgeSecretMatches/authRouteInternals pattern) and import them directly
in the test instead. Also drops the now-unused eslint-disable directives.
