Add DocxodusWeb: serverless redline & ticket management app

[JSv4]

Summary

Introduces DocxodusWeb, a new ASP.NET Core Minimal API web application for serverless deployment (Cloud Run, etc.) that provides document comparison and ticket management capabilities.

Key Changes

New Web Application (web/DocxodusWeb/)

• Program.cs — ASP.NET Core Minimal API setup with:

  • SQLite database context for ticket persistence
  • /api/compare — POST endpoint to upload two DOCX files and receive a redlined DOCX with tracked changes
  • /api/compare/html — POST endpoint to generate HTML preview of comparison
  • /api/tickets — GET/POST endpoints for ticket CRUD operations with pagination and filtering
  • /api/tickets/{id} — GET/PATCH endpoints for individual ticket detail and status updates
  • /api/tickets/{id}/files/{which} — GET endpoint to download original, modified, or redline files
  • SPA fallback routing for static frontend

• Data/TicketDbContext.cs — Entity Framework Core DbContext with:

  • Ticket model storing document metadata, file paths, comparison results, and revision counts
  • TicketStatus enum (Open, InProgress, Resolved, WontFix, Duplicate)
  • SQLite configuration with automatic migrations on startup

• Frontend (wwwroot/):

  • index.html — Single-page app with three tabs: Redline, Tickets, Submit Ticket
  • app.js — Client-side logic for form submission, API calls, modal interactions, and pagination
  • style.css — Modern, responsive design with CSS variables and mobile support

Configuration & Deployment

• DocxodusWeb.csproj — .NET 8 project with EF Core SQLite and Docxodus library dependencies
• Dockerfile — Multi-stage build for Cloud Run deployment with native font dependencies
• launchSettings.json — Local development profile on port 5050
• .dockerignore — Excludes build artifacts and app data from container

Notable Implementation Details

• Supports 100 MB file uploads via Kestrel configuration
• Automatic comparison on ticket submission with revision counting and error logging
• Persistent storage in DATA_DIR environment variable (defaults to ./appdata)
• Comparison log captures warnings/errors from the Docxodus library
• File downloads use proper MIME types and original filenames
• Form handling with DisableAntiforgery() for API endpoints
• Responsive UI with status badges, modals, and pagination controls

Integration
