feat(upload): resumable chunked upload protocol for large files — init(parts≤32MB)/status/complete endpoints with fingerprint-derived deterministic uploadId (same file resumes, no restart), sessions in BOOKS_DIR/.uploads with 24h sweep, frontend uploadBook auto-switches >16MB to 8MB parts (retry x3 in place, skip received); oversize single POST now reports honest 413 too_large instead of "multipart field 'file' required" (was MaxBytesReader abort mislabeled); UPLOAD_MAX_MB wired into both compose stacks (cap total, .env.example 2048), nginx body limit drops to 32m; testCfg limit 1MB, CJK/fullwidth-colon filename proven unaffected; e2e verified with 311MB real file (39 parts, sha1 match)
