feat(i18n): localize all 21 Image tool UIs to Bahasa (wave 2)

Every Image island renders Bahasa on /id/ via the lang prop + local TR:{en,id}
(LegacyLetter pattern). Covers convert/view/svg, monochrome, compress/resize/crop,
annotate, watermark/stamp/qr/merge, upscale, object-remove, portrait/face blur,
OCR + receipt scanner, camera, background remove, metadata scrub. Also threads lang
through shared OcrWorkbench/ReceiptFields/CameraCapture. Logic untouched;
format/brand/acronym terms kept; no 'alat'.
