Subject: [PATCH] refactor(editor): dedupe alt/caption controls via shared hook
 (F4)

Extract the ~110 duplicated lines into one parameterized
useImageTextFieldControl and make useAltTextControl/useCaptionControl
thin wrappers. Behavior identical; t("...") literals stay in the
wrappers so i18n extraction keeps working. sanitizeCaption still
exported for its unit test.
