feat: add 13-page institutional equity research report with automated PDF generation

- /report page: comprehensive 13~17 page report (Cover, TOC, Investment Snapshot,
  Company Profile, Financial Performance x4 charts, Quality Assessment, Operating
  Analysis, DCF 3-Scenario, Sensitivity Heatmap, Monte Carlo 5K, Tornado, Peer
  Comparison, Earnings Beat/Miss, Technical Summary, Disclaimer)
- Valuation engine: parallel POST to DCF / Sensitivity / Monte Carlo / Tornado /
  Reverse DCF using smart-defaults; fixed decimal vs percentage conversion for WACC
- Wall Street 10: institutional_report.py gathers DuPont, F-Score, DCF 3-scenario,
  Reverse DCF, peer comps into Gemini mega-prompt; POST /api/analysis/institutional
- SEC HTML viewer: fixed tempdir bug in sec_parser.py; full 10-K HTML now cached
  correctly; inject_sec_item_anchor_ids prefers later heading-like hosts over TOC
- Morgan Stanley Blue design system: navy/blue/gold print-optimised @media print CSS
  targeting A4 with page-break-after per section for PDF output
