feat: use firm's own templates as style guide for AI-drafted petitions

Belge Şablonları uploads now also get extracted_text (same OCR/office
pipeline as documents), and a new POST /api/drafting/generate builds
a real AI draft from the case's actual data (title, UYAP parties,
latest Dosya Özeti) — if the lawyer picks one of their own templates,
its extracted text is passed as a style/format reference only (the
prompt explicitly forbids copying the template's old case facts).
Dilekçe Hazırlama no longer fakes a draft with setTimeout.
