Resolve the white-label branding/domain config for a company — looked up by explicit company_id, by referral_code (resolved to its company), or, if neither is given, inferred from the request Referer host (subdomain + domain matched against domain_prefix/domain_name). When a record is found it also live-checks the custom subdomain status via AWS Amplify (persisting active/inactive), pulls the latest theme settings and the partner referral code, and rewrites logo/favicon paths to versioned S3 URLs.

Auth: Both — authentication (top-level authenticated group), role-agnostic account/white-label prefix. When you supply company_id it must sit inside your own account tree. A partner can therefore resolve any partner/account/location company beneath it, while an account user reaches only its own part of the account tree. With no company_id/referral_code the resolver falls back to the Referer host and returns whatever public white-label matches, regardless of role.

Rate limit: No rate limit.

Request

• Body (all optional; if none given, falls back to Referer host):

Response — { data. } envelope.

• status (string) — always "success".
• theme_settings (object|null) — latest RsUserThemeSetting row for the resolved company (id, user_id, company_id, theme_options JSON string, timestamps), or null if none.
• company (object) — { name } of the resolved company (empty string if unresolved).
• data (object|array) — the RsWhiteLabel row spread out (id, company_id, domain_name, domain_prefix, white_url, email, title, status, timestamps, nested company relation) with logo/login_logo/mobile_logo/favicon rewritten to versioned S3 URLs (or null), plus subDomainSetting (e.g. "verified" / "Domain not found!"). Returns an empty array [] when no white-label record is found.
• instruction_file (string) — asset URL to the domain-setup PDF.
• partner_referral (string|null) — referral code of the owning partner (only present when a white-label record is found).
