Update Project

Patch editable project-level fields surfaced in the Docs form.

Accepts description, competitors, and company_name (stored in Project.info['company_name']). The remainder of Project.info (industry, team_size, founded, location, …) is funnel-sourced and returned as-is for rendering. Per-segment targeting hints live on the Segment — see PATCH /segments/{id}.

company_name changes additionally bump email_templates_version on every segment in the project: the email-generation LLM prompt reads info.company_name (api/app_auto_gtm/email_rag._profile_offer_block) and its output is cached in generated_email keyed by version, so without the bump previews + future enqueues would keep the old name.
