/**
 * POST /api/notices/dismiss: hide one notice for the calling user + company.
 *
 * Dismissals are per user (a colleague still sees the notice) and per notice
 * id; ids embed a state discriminator (lib/notices/types.ts), so a dismissed
 * notice stays hidden only until the underlying condition changes: a NEW
 * failure mints a new id and surfaces again. Idempotent via upsert.
 *
 * No requireWrite: dismissing a personal notice is a per-user preference,
 * not a company-data mutation, so viewers may dismiss too.
