v1.1.1 - dashboard patch helper fix

Patch release for the dashboard startup regression reported in #14.

What changed:

• Executes the installed dashboard patch helper directly instead of invoking it through a non-guaranteed python alias.
• Relies on the helper's #!/usr/bin/env python3 shebang, matching the Python executable installed in the add-on image.
• Adds a regression assertion so the startup path does not reintroduce the bare python dependency.

Verification:

• python3 -m unittest discover -s tests -> 43 tests OK, 1 skipped
• python3 -m py_compile hermes_agent/dashboard-patches.py tests/test_dashboard_ingress_patches.py tests/test_multi_profile.py -> OK
• bash -n hermes_agent/run.sh hermes_agent/profile-init.sh hermes_agent/nginx-render.sh -> OK
