feat(aiturk): produce media through the AITURK CLI, stop adding the media MCP server (beta.13)

Owner decision (3 Oct 2026): where the AITURK CLI is available, TurkServis
models are reached through it, not MCP. The backend no longer writes a
`turkservis-media` MCP server into config.yaml on startup or when a member
endpoint is saved. Existing entries, including disabled ones, are left exactly
as they are. A bundled `aiturk-media` skill teaches the agent to list and run
media with `aiturk media`.
