feat: implement togglable debug log streaming for server stdout/stderr and client console logs

- Created server/utils/logCapture.js to intercept and buffer server output, stripping ANSI escape codes.
- Created server/middleware/logStreamAuth.js enforcing subnet IP filtering (LOG_ALLOW_SUBNETS), Emby session cookie, Basic Auth fallback, and X-Webhook-Secret header bypass.
- Created server/routes/debug.js with SSE streams /api/debug/server-logs, /api/debug/client-logs and batched POST /api/debug/client-logs. Exposes public configuration status at /api/debug/status.
- Integrated log capture and mounted debug routes in server/app.js and server/index.js.
- Implemented client/src/utils/clientLogCapture.js in the frontend SPA to hook console log/warn/error and flush batched console events.
- Documented all endpoints in OpenAPI server/openapi.yaml, ARCHITECTURE.md, and README.md.
- Wrote route integration tests and frontend console capture tests, with full validation in swagger-coverage.
