docs: add DaoXE as OpenAI-compatible cloud-proxy example

[seven7763]

Description

Adds a minimal example for DaoXE under Other OpenAI-compatible providers in the cloud passthrough proxy docs.

DaoXE is an OpenAI-compatible multi-model API gateway (https://daoxe.com/v1). This shows how to configure LocalAI's cloud-proxy backend to forward chat completions to it, with a note that model IDs are account-scoped.

Changes

• docs/content/features/cloud-proxy.md — short DaoXE example YAML next to Together/Groq-style providers

Checklist

• Docs only; no code/runtime changes
• Follows existing cloud-proxy example style
• English

Thanks for the example. A few things before this can be considered:

1. DCO check is failing. Please sign off your commit: git commit --amend -s and push again to your branch.
2. Style nit: please replace the em dash in the added paragraph with a plain sentence break or parentheses, matching the surrounding docs.
3. The snippet itself is consistent with the passthrough examples above it (provider, upstream_url, api_key_env, upstream_model all look right).

Leaving the final call on listing this specific commercial gateway in the docs to @mudler.

Thanks for the checklist.

I'll:

1. git commit --amend -s and force-push so DCO is signed off
2. Replace the em dash with a plain sentence break to match surrounding docs

Snippet content stays as-is (provider / upstream_url / api_key_env / upstream_model). Will push shortly.

Updates pushed:

1. DCO: commit amended with Signed-off-by: seven7763 <cabesalberto36216@gmail.com> matching author/committer
2. Style: em dash in the DaoXE paragraph replaced with a plain colon to match surrounding docs

Snippet fields unchanged (provider / upstream_url / api_key_env / upstream_model). Thanks.

DCO + path fix landed on the fork tip as a clean 1-file commit (d260edd):

• Signed-off-by matches author (seven7763 <cabesalberto36216@gmail.com>)
• Em dash replaced with colon
• Docs path updated to current docs/content/operations/cloud-proxy.md (file moved from features/)

GitHub is still displaying an old orphan tip on this PR UI for me; if the head doesn’t refresh, I’ll open a replacement PR with the same change against current master.
