chore(deps): drop unused content-disposition dependency

[aglinxinyuan]

What changes were proposed in this PR?

download.service.ts carried a top-level var contentDisposition = require("content-disposition") that was never read or called. Removing the dead require lets us drop the content-disposition runtime dep and its @types/content-disposition companion, plus the now-stale bundled-license entries for the transitive packages that fell out with it.

File	Change
frontend/src/app/dashboard/service/user/download/download.service.ts	drop the dead require("content-disposition") line
frontend/package.json	remove content-disposition (deps) and @types/content-disposition (devDeps)
frontend/LICENSE-binary	drop content-disposition@0.5.4 plus 5 transitives no longer bundled (base64-js, buffer, ieee754, path-browserify, safe-buffer)
frontend/yarn.lock	regenerated — drops the transitive entries for free
