fix: allow square brackets in zip path validation for Next.js dynamic routes (#4468)

* fix: allow square brackets in zip drop path validation for Next.js dynamic routes

ZIP uploads containing Next.js dynamic route files (e.g. app/api/[id]/route.ts,
pages/[slug].tsx) were rejected by readValidDirectory because the path regex
did not include square bracket characters.

* [autofix.ci] apply automated fixes
