fix(install): remove weather and music credential stubs from secrets template

config_secrets.template.json shipped ledmatrix-weather and music as
top-level keys; config_manager deep-merges secrets into the main config
on load, so the reconciler treated them as plugin config entries and
auto-installed both plugins on first web UI visit after a fresh install.

Remove both keys from the template and clear the inline fallback block
in first_time_install.sh so new installs start clean.
