ATS: add calorie counter flow

[goromal]

• Find (or make) client that can take a string of food description and estimate calories
  • THIS https://chatgpt.com/share/68773a8f-ae28-8009-b6c7-eea0a21761ed
  • Something that can be regression-tested
• Designated email
• Database for caching results so that I am not pinging an LLM multiple times for the same item
• Mechanism for determining when two queries are actually the same
• add a calorie prompt note to err high if uncertain
• This all gets implemented as a server with an API

Desired user flow:

• User texts description of food to the email
• For each text from same day, user receives a colorized bar indicating calorie pace, together with a second bar indicating user's pacing compared to historical data
• User has the ability to add historical data post hoc (includes data from some hours ago but same day) to backfill the record
• User can text HELP to the email and get directions
• User can visit a page on ATS to view historical record graphics
