Function resolveAllowedPlatform

resolveAllowedPlatform(
    requested: FeedbackPlatform | undefined,
    allowed: FeedbackPlatform[] | undefined,
    fallback: FeedbackPlatform,
): FeedbackPlatform
Resolves an outgoing feedback platform against the application's configured allowlist.
- When allowed is empty or undefined, requested ?? fallback is returned unchanged (preserving legacy behavior where the server remains authoritative).
- When requested is present and contained in allowed, requested is returned.
- When requested is absent or not in allowed, the first entry of allowed (or fallback if allowed is empty) is returned, and a warning is logged via console.warn in development builds so hosts learn of the configuration/allowlist mismatch.
Parameters
- requested: FeedbackPlatform | undefined
  The platform requested on the feedback draft or client configuration.
- allowed: FeedbackPlatform[] | undefined
  Target platforms enabled for this application (PublicAppConfig.allowedPlatforms).
- fallback: FeedbackPlatform
  Fallback runtime platform to use when no allowlist is configured or allowlist is empty.
Returns FeedbackPlatform
The resolved platform conforming to the allowlist when provided.
- Defined in src/utils/platform.ts:53
