chore(deps): bump mlflow from 3.14.0 to 3.15.1 in /src - #697

Sourced from mlflow's releases.

MLflow 3.15.1 is a patch release that includes bug fixes and documentation updates.

Bug fixes:

• [Model Registry] Skip env_pack on ARM client images (#24762, @​qyc)
• [Scoring / Tracking] Harden version parsing against missing/non-PEP440 versions on Databricks Serverless (#24799, @​PattaraS)

Documentation updates:

• [Docs] Clarify scorer versioning documentation (#24769, @​nihalmenon)

v3.15.0

MLflow 3.15.0 includes several major features and improvements

Major New Features

• 🧩 MCP Registry: A centralized catalog for registering, versioning, and sharing Model Context Protocol servers — with semantic-versioned configs, promotable aliases, tags, auto-discovered tools, and ready-made connection instructions for Claude Code and .mcp.json. Manage it from the UI, REST API, or Python!
• 🤖 MLflow Assistant enhancements: The in-app AI assistant now supports multiple LLM providers (Claude Code, Codex, and OpenAI-compatible/Gateway endpoints) chosen from a single settings page, displays live per-session token usage and estimated cost in the composer, and is easier to set up — mlflow agent setup can enable it in one prompt, with API keys stored securely in the Gateway's LLM Connections.
• 🗂️ Sharable table views: Save named views of the Runs table — capturing columns, order, widths, filters, and sort — and share them by URL.
• ⚡ Proxy-less artifact upload/download via presigned URLs: Large artifact transfers can now bypass the tracking server and talk directly to cloud storage (e.g. S3) through presigned URLs, cutting server load and timeouts on big files. We fall back to proxied transfer automatically for backward compatibility.
• 🖼️ Multi-modal attachments in LLM judges: {{ trace }} judges created with make_judge() can now see images captured in trace spans via a new get_span_image tool, which fetches attachments as base64 data URLs and passes them to multimodal models (Anthropic, Gemini, and OpenAI-compatible via litellm) — enabling evaluation of vision tasks, screenshots, and other visual content.

Other Assorted Features & Improvements:

• [Tracing / Tracking] Add Pydantic AI 2.x autologging support (#24721, @​B-Step62)

• [Evaluation / Gateway] Add sap-ai-core:/ provider for SAP AI Core Orchestration v2 with extra_headers support (#24356, @​shivamxtech)
• [Model Registry] [Model Registry] Migrate UC model artifact download to native temp-creds (#24576, @​AknA13)

• [Prompts / UI] Redesign Playground Tools settings with an Add-tools entry flow (#24102, @​tanghaoji)
• [] feat: add Cursor model catalog with Auto and Composer 2.5 pricing (#24078, @​TomeHirata)

Bug fixes:

• [Tracing] Compute mlflow.llm.cost for Claude Code plugin traces on Databricks (#24416, @​harupy)
• [UI] Fix artifact direct download capability checks in UI (#24748, @​B-Step62)
• [Tracing / UI] Refresh traces saved-view on load across multiple windows (#24746, @​joshuawong-db)
• [UI] Fix UnauthorizedError constructor message (#24729, @​mihir2921)
