ai-stack: add RAG/MCP stack to the optional-services picker, with dependency cascade

Browse Source 
User feedback: wanted chromaDB/rag-server/mcp-server included in the
optional-services picker added last commit, not just Gitea/Portainer/
Kiwix/InvokeAI/ComfyUI/Aider. Confirmed against the compose file's
depends_on chain before adding: open-webui only depends_on ollama (its
OLLAMA_BASE_URL connection works standalone), so none of these three are
actually required for regular chat — only Open WebUI's separate RAG tab
(routed through rag-server) and MCP tool-calling need them. Mealie's own
Ollama usage never touches this stack at all.

Bundled chromadb+rag-server+mcp-server as one option (7), not three
separate numbers — mcp-server depends_on rag-server depends_on chromadb,
so stopping only one of the three would leave the others running against
a dead dependency instead of a clean stop. Also added a cascade for the
existing kiwix option: mcp-server depends_on kiwix too (not just
rag-server), so stopping kiwix without also stopping mcp-server has the
same problem — now handled automatically with a dedup pass in case both
the kiwix cascade and option 7 add mcp-server to the stop list.

Verified all four cases in isolation: kiwix-only correctly cascades to
mcp-server, option 7 alone stops the right three, choosing both dedupes
to one clean list, and unrelated choices (gitea/portainer) are unaffected.
