Toggle the partner detail cards from read-only to editable in place. Edit
button in the PageHeader flips to Cancel + Save changes; cards expose
text inputs for name/domain/contact/billing, a 4-option segmented
control for status, and a 0–100 range slider for marginPct. Save sends
a PATCH diff (only fields that actually changed), refreshes the page
data, and exits edit mode. Cancel with unsaved changes confirms first.
Also tightens audit metadata: previously `Object.keys(dto)` on the
ValidationPipe-instantiated DTO listed every @IsOptional() field, even
when the request body didn't touch them. The partner.updated audit
event now records only the keys the operator actually sent.
- Partners list with name/domain/status/customers/margin + Create modal
- Partner detail: contract card, contact card, customers table, attach modal,
terminate (soft-delete) danger card
- Operator proxies for /partners + /partners/:slug/tenants
- platform-api: add partnerId Prop to Tenant schema. The field was being
silently dropped by Mongoose because the schema didn't declare it.
- tenants.service: rewrite update() to build $set/$unset explicitly and cast
partnerId via new Types.ObjectId(). Handles detach via $unset so the field
vanishes from the doc cleanly.
