Add real estate demo app (#23111)
## What
A new app under `packages/twenty-apps/internal/real-estate` that seeds a
real-estate demo workspace: buyers, sellers, agents, property listings,
showings, and an opportunity pipeline, with role-based access.
## Data model
- **Property** (custom object): address, price (currency), status
(coming soon / active / under offer / sold), type, beds/baths/surface,
photos, `listingAgent` and `sellerContact` relations to Person.
- **Showing** (custom object): scheduledAt, status, feedback, interest
rating, and `property` / `buyer` / `agent` / `opportunity` relations.
- **Person** (standard, extended): `personType` (Buyer / Seller /
Agent), budget min/max, pre-approved, desired area.
- **Opportunity** (standard, extended): `buyerStage` pipeline
(completing profile → showing → offer made → closing → won → lost), and
`buyer` / `seller` / `property` / `showings` relations.
## Views
- **Buyer Pipeline** — kanban on Opportunity grouped by buyer stage, one
card per buyer, scoped to real-estate deals.
- **Available (by price)** — properties sorted by price desc, excluding
sold.
- **Agents** / **Buyers** — filtered Person views.
- Record-page layouts for Opportunity and Showing so the relations
render on the detail pages.
## Roles
- **Broker** — full access (default).
- **Agent** — Property / Showing / Person / Note / Task, no Opportunity
access.
- **Seller** — read-only on their listing and its showings.
## Seeding
A synchronous post-install logic function seeds 4 agents, 12 sellers, 12
buyers, 30 properties across 5 cities, 24 showings, and 12 opportunities
(one per buyer), all wired through the relations.
