Address SonarQube security hotspots on the website:
- server/src/app.js: replace `contentSecurityPolicy: false` with a helmet CSP
tuned for the built React SPA (script-src 'self'; style-src adds 'unsafe-inline'
for React inline styles + the Google Fonts stylesheet; font-src gstatic; img-src
allows data:/https: for uploads, embedded body images and BRAND_* assets;
connect-src 'self' for REST+SSE). upgrade-insecure-requests is intentionally
omitted (TLS terminates at the proxy; keeps local `npm start` over http working).
The /api/docs Swagger UI route gets a scoped looser policy (inline script/style)
since swagger-ui-express injects an inline bootstrap.
- client/vite.config.js: disable the inline module-preload polyfill so code-split
builds keep `script-src 'self'` valid (RichTextEditor is a separate chunk).
- bot/src/app.js, server/src/internalApp.js: disable x-powered-by on the two
internal-only listeners (the public app already strips it via helmet).
- shardEvents dedupe key: SHA-1 -> SHA-256 truncated to 40 hex chars (fits the
existing CHAR(40) column, no migration; it is a content fingerprint, not a
security value). schema.sql comment updated to match.

- README rewritten for the completed frontend: full setup/run instructions
(Docker Compose, local dev with hot reload, prod build), pages/routes,
API endpoints, and a consolidated environment-variable reference
- Vite dev proxy now targets 127.0.0.1 (avoids the Windows IPv6-localhost
pitfall where the SPA could not reach the IPv4-bound API)
- Remove server/_setup.ps1 (a scratch script accidentally committed in the
previous frontend commit) and gitignore _*.ps1 scratch files
