docs: partner CTAs on high-traffic pages (workflows, data-model, docker-compose) (#22808)

## Summary

Follow-up to #22719 (merged), which added partner-marketplace CTAs to
four **high-intent, low-traffic** docs pages (SSO, both migration
guides, implementation services).

Reviewing the docs' **top-visited pages** showed none of those four rank
in the top ~20 — they're the high-intent tail, which is correct, but
small reach. This PR extends the same pattern to three **high-traffic
pages that also carry buying intent**, without touching the pure
top-of-funnel intros/quickstarts (volume without intent → a CTA there is
just noise).

Same conventions as #22719: Mintlify-native `<Tip>` callouts,
partner-first with `contact@twenty.com` secondary, directory deep-linked
via `?categories=<scope>` and tagged with `?ref=docs-*`. No new snippet;
no `docs.json`, navigation, or translation (`l/`) changes.

## Pages changed — screenshots (one per page)

### 1. `/user-guide/workflows/overview` (~593 views)
New `## Need Help?` two-bullet `<Tip>` → **Done for you** (Solutioning
partner) / **Onboarding pack** (Workflow Creation). Maps 1:1 to the
named onboarding service.

/>


### 2. `/user-guide/data-model/overview` (~954 views)
Replaced the plain "Need Help?" line with a two-bullet `<Tip>` → **Done
for you** (Solutioning partner) / **Onboarding pack** (Data Model
Design). Keeps the existing Implementation Services link.

/>


### 3. `/developers/self-host/capabilities/docker-compose` (~2421 views)
New `## Managed Hosting` single-line `<Tip>` → *find a certified Twenty
hosting partner* (Hosting), contact fallback. Framed as a lighter
"prefer not to run it yourself?" alternative — deliberately low-pressure
for the DIY self-host audience.

## Notes for reviewers

- Page-selection rationale: intent × volume. Kept the four intent-tail
pages from #22719; added the highest-traffic pages that also carry a
natural partner-buying moment (self-host → Hosting; workflows /
data-model → Solutioning). Intros/quickstarts/contribute pages
intentionally left untouched.
- **Attribution caveat (unchanged from #22719):** twenty.com's analytics
(Cloudflare Web Analytics) is path-based, so `?ref=` is not measurable
yet. Per-page measurement via a `/go/*` redirect Worker remains a
planned, separate follow-up (out of scope here).
- `mintlify validate` passes.

Opened as a draft.
