📝 Walkthrough

Walkthrough

EventMaterialForm was converted to a functional React component using hooks. State synchronization, form handlers, submission, conditional rendering, media uploads, and regression tests were updated.

Changes

Event material form

Layer / File(s)	Summary
Hook state and prop synchronization src/components/forms/event-material-form.js	React hooks replace class state wiring. Effects synchronize entity and validation errors. The form derives optional media configuration.
Form behavior and media rendering src/components/forms/event-material-form.js, src/components/forms/__tests__/event-material-form.test.js	Handlers update fields and upload metadata, file removal clears metadata, submission passes entityState, and tests verify stale values are cleared when the entity changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

@santipalenque This PR rewrites the component's entire state-reset mechanism (class componentDidUpdate/shallowEqual → useEffect([entity])/useEffect([errors])) to fix the "adding new material shows previous description" bug, but ships with no test exercising that reset path — event-material-form.js has never had its own test file, and edit-event-material-page.test.js fully mocks EventMaterialForm, so it can't catch a regression here.

Without a reproducing test, if this reset logic is touched again later, the exact bug this PR fixes (stale entity/description carrying over when switching from an existing material to "add new") can silently reappear with nothing in the suite to flag it.

Suggested fix: add src/components/forms/__tests__/event-material-form.test.js covering the reset case — render with a populated entity (non-empty description), then rerender with a fresh/default-shaped entity prop (as happens on navigating to "add new"), and assert the description/name fields no longer show the old value.
