refactor(eas-cli): Remove npx expo invocations and config/entitlements fallbacks

[kitten]

See: https://exponent-internal.slack.com/archives/C017N0N99RA/p1758469493137929
Resolves: expo/expo#40227

Why

Note

There's still a lot of leftover reliance on @expo/config (outdated), @expo/prebuild-config, and some other internals, which are prone to failing and not being updated. A lot of them don't have replacement code paths that are obvious but stood out to @byCedric when implementing some Launch features and replicating/replacing some logic from eas-cli

All invocations of npx are prone to failure and unnecessary:

• npx expo install is redundant if we can invoke the Expo CLI directly (which forks if needed automatically)
• npx expo config --json is unreliable, if npx adds additional output to the standard output. It also can fail if there's a global provider of expo, another expo in the npm-resolved PATH, or for various other reasons
• the same applies to the entitlements call

Additionally, we have a few fallbacks that are invalid. The entitlements fallback doesn't work and replaces the failed npx expo config command with obscure output, failing to also print its Log.warns in some cases, which are confusing.

The @expo/config fallback has to be left in place currently as there's no prerequisite of expo being installed (which there should be) for getExpoConfigInternalAsync to be invokable. The check for isExpoInstalled is also faulty as it doesn't resolve expo but instead checks the package.json, but to keep this PR leaner, this isn't addressed here.

The fallbacks are generally for older versions of the SDK which are now unsupported.

How

• Replace all npx expo invocations with a direct expo CLI invocation (code already existed for this)
• Remove entitlements and config error fallbacks, which were confusing

Test Plan

Most of these changes are speculative and untested right now.

Thanks for doing this!! I’ll have a look to see if the tests can be improved in a separate PR, and also have a look at removing some of the fallbacks that are no longer needed with the current supported Expo SDK.
