Add secrets.yaml and unify variable substitution sources (#24044)

* add secrets.yaml and merge substitution sources by precedence

FRIGATE_ENV_VARS was built once at import from container env and /run/secrets, and the environment_vars validator overwrote it unconditionally, so the block beat the deployment and nothing could be re-read. Sources are now separate dicts merged lowest to highest (environment_vars, secrets.yaml, container env, credentials directory), re-read at the top of every parse, and a collision warns once naming the winner. An undefined {FRIGATE_*} raises a ValueError subclass so pydantic reports the field instead of a KeyError traceback.

* use the shared substitution namespace in go2rtc config

The generator rebuilt the namespace itself from os.environ and a hardcoded /run/secrets, so it never saw environment_vars or CREDENTIALS_DIRECTORY, and str.format made any stray brace fatal. It now installs the FRIGATE_ names from environment_vars and substitutes streams the same way every other field does.

* read the exec override from an import time snapshot

environment_vars is exported into os.environ, and is_go2rtc_arbitrary_exec_allowed read os.environ live, so the config file could enable exec sources. Snapshot the variable at import, which runs before any config is loaded.
