Part of the final clean-up (REV-144). These are small fixes that only change error paths, plus some dead code removal.

Fixes

• Ctrl+C at a y/N prompt (ui/terminal.ts): it used to crash with TypeError: Cannot read properties of undefined (reading 'response'). Now it counts as "no", so the command prints its usual "… cancelled." message and exits 0. Only an actual Ctrl+C is handled this way. Any other prompt error still fails the command exactly as before, so a script can't mistake it for a cancel.
• Temp zip delete after an upload (management-sdk.ts): if the file was already gone, unlinkSync threw inside the superagent callback, giving an uncaught ENOENT and a release promise that never settled. It now uses rmSync({ force: true }), best effort, so the upload's result always comes back.
• Failed zip (management-sdk.ts): if zipping a release folder failed, a randomly named .zip was left in the current folder. It's deleted now.

Dead code

• initiateExternalAuthenticationAsync(action, url) never used action and wasn't async. It's renamed openLoginPage(url), and loginWithExternalAuthentication loses the unused action too. The URLs are built exactly as before.
• types/rest-definitions.ts no longer re-exports itself.

Verification

Check	main	This branch
Real terminal: Ctrl+C at "remove this app? (y/N)"	TypeError stack trace, exit 1	"App removal cancelled.", exit 0
No terminal (stdin closed) at the same prompt	exits 0 silently	same
45 CLI commands against a fake server	Same output and server requests	Same output and server requests

• New tests: test/terminal.ts covers y, an empty answer, Ctrl+C and other prompt errors. test/management-sdk.ts covers the partial zip being deleted and an upload whose zip is already gone. The three fix tests fail on main.
• Tests: all 165 pass on macOS and on Linux (Docker, Node 20.19.0).
• Build, lint and format: tsc, lint and format are clean.
