fix(programs): remove selected child rows

[MinHyeong-Lee]

What changed

• Remove selected Program Course and Program Member rows by checking every supported row identity.
• Add focused tests for selections keyed by course, member, or child-row name.

Why

The Program lists use course and member as their row keys, while persisted child rows also have a name. The previous filter used expressions such as row.name || row.course. Once name existed, the selected course or member value was never compared, so clicking Delete left persisted rows in the Program.

The new helper checks both possible identities independently, matching the selection keys emitted by the list components while retaining support for child-row-name selections.

User impact

Program managers can delete selected courses and members from an existing Program and save the result.

Validation

• yarn test src/tests/programSelection.test.ts src/tests/programForm.test.ts — 15 tests passed
• yarn build — passed

Confidence Score: 5/5

The PR appears safe to merge.

The helper correctly handles persisted and unsaved Program rows, and no reachable regression or rule violation was identified.
