/**
 * Creates or edits a document
 *
 * Rules:
 * 1. Routes/paths are immutable (they can be deleted)
 * 2. When a path is updated for a document, make a new route and set the path_id to the new route
 * 3. When a draft is inserted for a document:
 *    - If there is no existing draft: copy over every undefined/null field from the current saved version
 *    - If there is an existing draft: update the fields for the draft
 * 4. When a draft is "saved" (published=true), it becomes the new current version and the old record is deleted
 *
 * Supports two call patterns:
 * - 3-param: upsert(client, query, input) - explicit query and input
 * - 2-param: upsert(client, inputWithQuery) - combined query and input in one object
 *
 * @param client Database client
 * @param queryOrInput Query to find the document, or combined query+input object
 * @param input Document data to update (optional if using combined object)
 * @returns Object with current (saved) and/or draft versions of the document
