 * Resolve `legalApiBaseUrl` from company-scoped plugin config.

 * ⚠️ Plugin config became company-scoped in @paperclipai/server 2026.722.0
 * (migration `0164_plugin_config_company_scope`). A bare `ctx.config.get()` now
 * throws `company context is required` unless the host can derive the company
 * from the current invocation — which it CANNOT during `setup()`, because
 * worker initialisation belongs to no company. Reading config at startup is what
 * made the whole plugin fail to activate on the 722.0 upgrade.
 *
 * So: never call this from setup(); call it from a handler, passing the
 * companyId that handler was given. Tool handlers get `runCtx.companyId`; data
 * handlers get `params.companyId`. Scheduled jobs have no company at all, so
 * they fall back to probing the companies we know about.
