Add training corpus UI with Nevo proofreading pipeline

- New proofreader service strips Nevo editorial additions (front matter,
  postamble, page headers, watermarks, inline codes) from DOCX/PDF/MD
- PDF pages use Google Vision OCR for clean Hebrew RTL extraction
- New training page at #/training with drag-and-drop upload, automatic
  metadata extraction (decision number, date, categories), reviewable
  preview, and style pattern report grouped by type
- API endpoints: /api/training/{analyze,upload,corpus,patterns,
  analyze-style,analyze-style/status}
- Fix claude_session.query to pipe prompt via stdin, avoiding ARG_MAX
  overflow when analyzing 900K+ char corpus
- CLI scripts for batch proofreading and corpus upload

"""Batch upload proofread training corpus to style DB.
Two-phase workflow:
--preview Extract metadata from all .md files, print review table, don't upload
--upload Actually upload all files (with optional --only FILE to run one)
Metadata extraction:
* decision_number: from filename (ARAR-YY-NNNN / ערר NNNN-YY) or decision date year
* decision_date: from "ניתנה ... <day> ב<Hebrew month> <YYYY>" near end of text
* categories: keyword heuristics on body text
