Addresses #16455.

Changes

• Initialize default entitlements in a Set to include all features
• Initialize entitlements' Warnings and Errors fields to arrays rather than nils.
• Minor changes in formatting on the frontend

Reasoning

I had to change how entitlements are initialized to match the codersdk generated types, which the frontend assumes are correct, and doesn't run additional checks on.

• features: Record<FeatureName, Feature>: this type signifies that every FeatureName is present in the record, but on main, that's not true if there's a telemetry required error
• warnings: readonly string[]; and errors: readonly string[];: these types mean that the fields are not null, but that's not always true

With a valid license, the LicensesEntitlements function ensures that all features are present in the entitlements. It's called by the Entitlements function, which is called by api.updateEnittlements. However, when a license requires telemetry and telemetry is disabled, the entitlements with all features are discarded in an early exit from the same function. By initializing entitlements with all the features from the get go, we avoid this problem.
