Classify webhook subscription modules as configuration experience

[isaacroldan]

Part 2 of 8 — splitting #8040.

WHY are these changes introduced?

The active-app-version classification (#8055) derives each module's create/update/delete status from its experience. Webhook subscription modules must be treated as configuration, not standalone extensions, or they surface incorrectly in the deploy prompt.

WHAT is this pull request doing?

normalizeExperience now receives the spec identifier and maps the webhook subscription spec to the configuration experience. Private function; all three call sites updated in-file. No consumer reads the new classification yet, so behavior is unchanged.

How to test your changes?

pnpm --filter @shopify/app exec vitest run src/cli/utilities/developer-platform-client/app-management-client.test.ts

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.
