feat(training): Style Studio — upload, rich corpus, lessons, curator portrait, chat

Six-phase upgrade of /training from a read-only dashboard into a full
Style Studio for managing Daphna's style corpus.

- Upload Sheet on /training: file → proofread preview → commit (no more
  CLI-only `upload-training` skill).
- Rich corpus metadata: GET /api/training/corpus returns summary, outcome,
  key_principles, page_count, parties (regex), legal_citation, lessons_count.
  PATCH endpoint for chair edits. CorpusDetailDrawer with 4 tabs (details
  /content/lessons/patterns) replaces the bare table row.
- LLM metadata enrichment: style_metadata_extractor + MCP tools
  (style_corpus_enrich, style_corpus_pending_enrichment) fill summary
  /outcome/key_principles via claude_session (free, host-side).
- Per-decision lessons: new decision_lessons table + 4 REST endpoints +
  LessonsTab in drawer; hermes-curator now auto-posts findings as
  decision_lessons(source=curator).
- Curator Portrait tab: prompt rendered with link to Gitea, recent
  curator findings, style_analyzer training prompts, propose-change
  form that writes proposals to data/curator-proposals/ for manual
  chair review (no auto-mutation of the agent file).
- Style chat tab: SSE-streamed conversations with the style agent.
  New host-side pm2 service (legal-chat-service, port 8770) wraps
  claude CLI with stream-json + --resume continuation; FastAPI proxies
  via host.docker.internal. Zero API cost — uses chaim's claude.ai
  subscription. chat_conversations + chat_messages persist history.

Architecture: keeps the existing rule that claude_session only runs
on the host (not the container). The new legal-chat-service is the
canonical bridge between the container and the local CLI for the chat
feature; everything else (upload, metadata, lessons) stays within the
container's existing capabilities.

Audit script (scripts/audit_training_corpus.py) included for verifying
which corpus rows still need enrichment.

+"""legal-chat-service — host-side SSE bridge to ``claude`` CLI.

+Runs as a pm2-managed process on the host (port 127.0.0.1:8770 by default).
+The legal-ai FastAPI container proxies chat requests to it via
+``host.docker.internal:8770``.
+
+Why a separate service:
+    The chat needs real-time streaming + multi-turn session continuation
+    (``claude --resume <session_id>``). The container can't run the
+    claude CLI (no binary, no claude.ai credentials). Splitting this out
+    keeps the architectural rule of ``claude_session.py`` intact while

+ *     We never let the chair edit full_text from the UI; corrections happen
+ *     by re-uploading via the Upload dialog.
+ *   - "מה למדנו" — per-decision lessons (Phase 4 placeholder for now).
+ *   - "דפוסים" — style_patterns scoped by appeal_subtype.
+ *
+ * Why a Sheet, not a Dialog: the drawer needs to coexist with the corpus
+ * table so the chair can scan multiple decisions without losing context.
+ * Sheet (side: "left" in RTL = right edge in LTR) gives that without
+ * stealing the entire viewport.

+"""Compose the system prompt the style-chat agent receives.
+
+The chat runs against the local ``claude`` CLI on the host (via
+legal-chat-service). We assemble a once-per-conversation system block
+that gives the agent everything it needs to discuss decisions in
+Daphna's voice:
+
+  - The style guide (``skills/decision/SKILL.md``) — how she writes
+  - The lessons file (``docs/legal-decision-lessons.md``) — what we've
+    learned across the corpus
+  - The corpus-analysis report (``docs/corpus-analysis.md``) — the
+    structural map of 24+ decisions
+  - A summary of every style_corpus row (number, date, subjects,
+    chars + summary if extracted) so the agent can reason about the
+    whole corpus without us shipping all of it inline
+  - Optional: when the conversation is scoped to a specific decision
+    (``style_corpus_id``), append its full_text so the chat can dive
+    into the text directly
+
+Sent **once**, when the conversation is first created. On subsequent
+messages the legal-chat-service uses ``claude --resume <session_id>``
+and the on-disk CLI session keeps the system context intact — no need
+to re-ship the 100K+ chars of skills + lessons every turn.
