feat(epic8+docx): complete Inbound Webhooks CRM Inbox + Full DOCX Document Management

EPIC 8 - INBOUND WEBHOOKS & CRM INBOX ✅
========================================
Backend:
- Add is_read field to memos table with auto-migration
- Inbound webhook endpoint: POST /inbound_webhooks/{workspace_id}
- Inbox endpoints: GET /users/{id}/inbox/unread_count, GET /users/{id}/inbox/memos
- Webhook payload formatting (title+body → markdown, arbitrary → bullet list)
- Optional secret verification via X-Webhook-Secret header
- Database indexes: idx_memos_is_read, idx_memos_workspace

Frontend:
- Inboxes.tsx: Two tabs (Notifications + Unread Memos)
- useInboxUnreadCount hook with 60s refetch
- useMarkMemoAsRead mutation
- Navigation badge: notifications + unread memos count
- i18n: inbox.* keys (en/vi)

DOCUMENT MANAGEMENT (DOCX/PDF) 🆕
==================================
Backend:
- New table: cuccu_documents with full schema
- DocumentService: upload, list, get, update, delete, process, import_to_memo
- AI enhancement via OpenAI (tag extraction + summarization)
- python-docx integration for text extraction
- Status workflow: PENDING → PROCESSING → COMPLETED/FAILED
- API routes: /documents/upload, /documents, /documents/{id}, /documents/{id}/process, /documents/{id}/import

Frontend:
- New page: DocumentsPage (route: /app/documents)
- Components: UploadArea, DocumentList, DocumentCard, PreviewPanel
- Hooks: useDocuments, useDocumentUpload, useDocumentProcess, useDocumentImport
- AI enhancement panel with toggles (extract tags, generate summary)
- Drag-and-drop file upload with validation
- Status badges, tag display, content preview
- Workspace isolation support
- Full i18n support (en/vi)

Files changed:
- Backend: 15+ files (new: api/documents/, common/sqlite_client.py updates, schemas, services, config)
- Frontend: 20+ files (new: components/Documents/, hooks/useDocuments.ts, docxService.ts, pages/DocumentsPage.tsx)
- Tests: test_inbox.py (5 tests passing)
- Plan docs: epic-8-inbound-webhooks-crm-inbox-done.md, docx-frontend-detailed-plan.md

+
+Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.
+
+**Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment.
+
+## 1. Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+Before implementing:
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them - don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+## 2. Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+## 3. Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it - don't delete it.
+
+When your changes create orphans:
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+## 4. Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
