fix(browser): fix Camofox JS eval endpoint, userId, and package rename (#9774)

- Fix _camofox_eval() endpoint: /tabs/{id}/eval → /tabs/{id}/evaluate
  (correct Camofox REST API path)
- Add required userId field to JS eval request body (all other Camofox
  endpoints already include it)
- Update npm package from @askjo/camoufox-browser ^1.0.0 to
  @askjo/camofox-browser ^1.5.2 (upstream package was renamed)
- Update tools_config.py post-setup to reference new package directory
  and npx command
- Bump Node engine requirement from >=18 to >=20 (required by
  camoufox-js dependency in camofox-browser v1.5.2)
- Regenerate package-lock.json

Fixes issues reported in PRs #9472, #8267, #7208 (stale).
