The app put hardcoded references to localhost in the index.html file, need to dynamically generate

Currently the server is accepting redundant ids on all data types - logs, AQM readings, spiro events, etc. It is trusting that the client isn't sending redundant ids and not checking, and it should check. Best behavior would be to accept what is unique and reject the rest. Also need to check for a primary key in the DB, must not be one. It should be id and device_id and timestamp (in case the app was reset)
