Subject: [PATCH] Refactor database migrations and schema for `Chat` and
 `Setting` tables

- Removed the unique constraint on `remoteJid` and `instanceId` in the `Chat` model to prevent potential migration failures due to existing duplicates.
- Deleted the old migration file for adding `wavoipToken` to the `Setting` table and created a new migration that includes a check for the column's existence before adding it, ensuring smoother migration processes.
- Updated migration logic to clear previous migrations related to `wavoip_token` to maintain a clean migration history.
