Migration: add opp-inactive to opportunity_status_enum

[nadavosa]

Summary

Add `opp-inactive` to the PostgreSQL `opportunity_status_enum` type and create a TypeORM migration for it.

Motivation

• Notion data has opportunities with statuses: Cancelled by us, Cancelled by RAC, Cancelled by refugee, Inactive — these should map to `opp-inactive` (distinct from `opp-past` = completed/done).
• FE PR Fix:Opportunity statuses #332 fe#333 has an Inactive status option that currently maps to `opp-past` as a workaround.
• SDK needs `INACTIVE = "opp-inactive"` added to `OpportunityStatusType` (tracked separately).

Migration to create

File: `src/data/migrations/-add-opp-inactive-status.ts`

```ts
import { MigrationInterface, QueryRunner } from "typeorm";

export class AddOppInactiveStatus implements MigrationInterface {
name = "AddOppInactiveStatus";

public async up(queryRunner: QueryRunner): Promise {
await queryRunner.query(
`ALTER TYPE "public"."opportunity_status_enum" ADD VALUE IF NOT EXISTS 'opp-inactive'`
);
}

public async down(queryRunner: QueryRunner): Promise {
// PostgreSQL does not support removing enum values directly.
// To rollback: recreate the enum without opp-inactive and cast all columns.
// Only do this if no rows use opp-inactive.
}
}
```

No endpoint changes needed

The existing `PATCH /opportunity/:id` endpoint already accepts `statusOpportunity` from the SDK enum — once the SDK is updated and this migration runs, it will accept `opp-inactive` automatically.

Depends on

• SDK issue: Add INACTIVE to OpportunityStatusType enum

Unblocks

• need4deed-org/fe PR prepare reference data #333
• Notion data seeding script (cancelled opportunities)
