fix(media): release the upload action when the file picker closes

[MatthieuVillebrun]

What breaks

Fixes #540

Clicking Upload media, then dismissing the OS file picker, permanently disables the button. The picker never reopens until the page is reloaded. The same happens after a successful upload.

Why

ItemActionsToolbar opens the picker indirectly: the button sets context.actionInProgress, and a watcher reacts by clicking a hidden <input type="file">. Reopening therefore requires that state to go back to null first.

UploadMedia is in neither oneStepActions nor twoStepActions (utils/context.ts:3-4), so the re-entrancy guard in useContext.ts:83-95 turns any second dispatch into a bare return while the action is still marked in progress. And nothing marks it finished:

What the fix does: releases the action at both terminal outcomes, each where the codebase already does that: unsetActionInProgress() at the end of the raw handler (matching the two Create handlers), and @cancel on the input (mirroring ItemCardForm's dismissal paths).
