Add --no-input to all commands

[gonzaloriestra]

WHY are these changes introduced?

Closes shop/issues-develop#23696

Scripts and agents need to disable interactive behavior independently from output format.

WHAT is this pull request doing?

• Adds --no-input alongside the existing global flags.
• Disables prompts, browser launches, keypress handling, and REPL input.
• Returns actionable errors when required input is unavailable.
• Keeps piped input available.

How to test your changes?

1. Run shopify app deploy --help and confirm --no-input is listed.
2. Run shopify app deploy --no-input and confirm it shows the expected error.

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.

New type declarations

packages/cli-kit/dist/public/node/no-input.d.ts

    'no-input': import("@oclif/core/interfaces").BooleanFlag<boolean>;

 * @param environment - Environment variables to inspect.
