Fixes company-contact name drift when a company is renamed or deleted. Closes: N/A ## Why Contacts keep a denormalized `additional_attributes.company_name` for display and filtering. Company rename/delete flows could leave that copied value stale even though the actual `company_id` relationship changed. ## What changed - Enqueues an async company contact-name sync job when a company name changes. - Moves company deletion into `Companies::DeleteJob`. - The delete job unlinks linked contacts, clears only the copied `company_name`, and then deletes the company. - Uses bulk JSON updates for the cleanup path so contact records are not saved, which avoids contact update callbacks, webhook dispatch, and automation side effects. ## How to test - Link a contact to a company, rename the company, and confirm the contact company name updates after the job runs. - Delete a company with linked contacts and confirm the delete job removes the company, unassigns linked contacts, and preserves other contact additional attributes. --------- Co-authored-by: Sony Mathew <sony@chatwoot.com> Co-authored-by: Sony Mathew <2040199+sony-mathew@users.noreply.github.com>
