fix: generate server-side previews for all non-browser formats

SERVER_PREVIEW_EXTENSIONS was missing TIFF, DDS, DPX, EPS, FITS, JP2,
PBM/PGM/PPM, QOI, SVGZ, CUR, and many RAW variants. The server
already had decoders for all of them but the client never triggered
the preview fetch, so users saw "Preview not available" instead.
