shad 973aa9c15b fix(security): lock CSP script-src to self (no unsafe-inline/unsafe-eval)
Oracle round-9 hard blocker: live CSP advertised script-src 'self'
'unsafe-inline' 'unsafe-eval'. Verified the Vite build emits zero inline
<script> tags (only external module script) and no bundled dep uses
new Function / eval (reactflow / leaflet / zustand / dagre / cmdk /
framer-motion all clean).

- nginx.conf script-src reduced to 'self'.
- img-src extended for OSM tiles (https://*.tile.openstreetmap.org) and
  leaflet marker images served from unpkg.

Also (Oracle round-9 second blocker) chat_sidebar QA now creates a
thread + sends a message before asserting, then strict-asserts
threadRowCount >= 1 AND previewRows === threadRowCount AND
timeBadges === threadRowCount. No more vacuous PASS when sidebar is
empty.
