Fix repeated event config diffs when API versions are inherited - #8677

WHY are these changes introduced?

shopify app deploy reports unchanged events configuration as updated when a subscription omits api_version and inherits [events].api_version. The server stores the inherited version on each subscription, while the CLI compares it with a local config that still omits the field.

WHAT is this pull request doing?

Resolve inherited subscription versions in the existing local-to-remote events transform, alongside relative URI resolution. Deploy comparison and upload then use the same effective versions as the server, without modifying the local TOML or requiring a server change.

Explicit overrides remain intact. Regression tests cover unchanged inherited and explicit versions, changing or removing an override, and changing the default version.

How to manually test your changes?

Use an app whose TOML sets [events].api_version and omits api_version on an event subscription:

pnpm shopify app deploy --path /path/to/app
pnpm shopify app deploy --path /path/to/app

The second deploy should show no events update. Setting a different subscription version, or removing an override that differs from the default, should still show an update.
