fix: MCP server Docker deployment, healthchecks, and minor fixes

MCP server:
- Fix Prisma imports from stale client-generated path to @prisma/client
- Switch schema from SQLite to PostgreSQL for Docker compatibility
- Add prisma generate step to Dockerfile with proper binaryTargets
- Include index-sse.js in Docker build (was excluded by .dockerignore)
- Install openssl and libc6-compat in Alpine image for Prisma runtime

Docker:
- Fix memento-note healthcheck (wget unavailable in bullseye-slim)

Minor fixes:
- scrape.service SSRF protection, middleware route coverage
- canvas-board and note-input type fixes
- next.config turbopack and devIndicators adjustments
