feat: add Augur Investment Analysis page (17 investor personas)

[BruceLanLan]

Summary

This PR integrates Augur — a multi-agent investment analysis system — as a native page in Hermes Web UI.

• Adds /hermes/investment route with InvestmentView.vue
• Sidebar entry under the Agent group with a pulse-chart icon
• 17 investor personas: Buffett, Graham, Lynch, Dalio, Munger, Soros, Marks, Cathie Wood, Fisher, ARPS, Aschenbrenner, 大宇, Thiel, 段永平, 张磊, 李录, 但斌
• Calls Augur's local FastAPI (http://localhost:8000) — URL is configurable per-session
• Graceful fallback if Augur is not running (clear error message with startup instructions)
• Uses Naive UI (NCard, NGrid, NTag, NSpin, NStatistic, NAlert, NInput, NButton), Vue 3 Composition API, and existing Hermes patterns
• i18n key sidebar.investment added to all 9 supported locales (en, zh, zh-TW, ja, ko, de, es, fr, pt)

Augur setup (prerequisites)

git clone https://github.com/BruceLanLan/augur.git
cd augur && pip install -r requirements.txt
python3 -m dashboard.app  # starts on :8000

Test plan

• Start Augur (python3 -m dashboard.app)
• Open Hermes Web UI, navigate to Investment Analysis sidebar item under Agent group
• Enter ticker "AAPL", click Analyze
• Verify 17 agent cards appear with signals (bullish/neutral/bearish) and score bars
• Verify consensus banner shows ticker, overall score, and signal tag
• Test without Augur running — friendly error message should show with startup instructions
• Verify sidebar item shows correctly in collapsed (icon-only) mode
• Switch language — verify i18n label renders correctly in all supported languages
