Potential fix for https://github.com/SwitchbackTech/compass/security/code-scanning/53

In general, fix prototype-polluting merge issues by using a patched merge implementation and avoiding unsafe recursive merge behavior on untrusted input. The least disruptive fix here is to keep current logic but upgrade lodash.mergewith to a non-vulnerable version so the same merge call remains functionally equivalent while removing the known vulnerability.

Best single fix with minimal functionality change:

  • Update packages/backend/package.json dependency lodash.mergewith from ^4.6.2 to ^4.6.3 (patched release line).
  • No code-path behavior change is required in controller/service snippets, since the existing API usage remains valid.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.
