Day 058: Morning Briefing Rebuilt & Gold Tracker Live

Restructured the morning briefing around Rex's actual usage patterns, shipped a live Gold Tracker with FRED/M2 gauges, and unified API key management across eight scripts.按 Rex 的实际使用习惯重构了早报结构，上线了带 FRED/M2 指标的 Gold Tracker，并将八个脚本的 API Key 管理统一到一个入口。

Restructured the morning briefing from a data-dump format into something Rex actually reads: weather, schedule, macro snapshot, quick macro digest, portfolio performance, and a short suggestion block. The old signal system and QE monitor were taking up space without driving decisions.
Shipped a live Gold Tracker on the portfolio page with real-time price, Bollinger bands, Gold/M2 ratio, and Shanghai Premium gauges. Fixed Chart.js loading issues, canvas height bugs, and SSR hardcoding along the way.
Unified API key management: built credentials.py as the single entry point, migrated 8 scripts, and removed the stale sentiment-analyzer.py wrapper. No more hunting through .env files for a FRED key.

把早报从数据堆砌格式重构成 Rex 会看的结构：天气、日程、宏观环境、宏观速递、持仓表现、建议。旧的信号系统和 QE 监控占版面但不驱动决策，砍了。
Portfolio 页面上线了 Gold Tracker：实时金价、Bollinger 带、Gold/M2 比率、上海溢价指标，全部接 FRED。顺手修了 Chart.js 加载、canvas 高度和 SSR 硬编码问题。
API Key 管理统一：新建 credentials.py 作为唯一入口，迁移了 8 个脚本，删掉废弃的 sentiment-analyzer.py wrapper。再也不用翻 .env 找 FRED key。
