Closes#370 (reported by JohnBaumb).
The /api/settings endpoint and three siblings (/log-level,
/config-status, /verify) had no auth check — any logged-in profile
could read or modify service tokens, OAuth secrets, and API keys.
Cin's "minimum" suggestion from the issue: gate to admin profile.
Added an `admin_only` decorator near `get_current_profile_id` that
returns 403 when the current profile isn't admin (id=1). Applied
to all four endpoints.
Auth model note (documented in the decorator docstring): SoulSync's
existing model is "trust local network" — single-admin / no-multi-
profile installs default `get_current_profile_id()` to 1, so the
gate is a no-op for solo users. The decorator is meaningful in
multi-profile setups where non-admin sessions exist. Tightening to
real per-request auth is out of scope.
Did NOT consolidate with api/settings.py (Cin's "better" suggestion):
that endpoint uses API-key auth (for external tools), the web_server.py
copy uses session/profile auth (for the web UI). Different consumers,
different auth models — merging would break one or the other.
603 tests pass.
