Address findings from the pre-merge review:
- Form (TSB) now computes only when ctl/atl are numeric (isinstance guard),
so a non-numeric value can no longer raise out of format_wellness_entry and
take down the entire wellness render.
- The Date line uses `or` chaining so a present-but-null `date` falls back to
`id` instead of rendering "Date: None".
- update_wellness injects the written date into the API echo when it lacks
id/date, so the confirmation body can't read "Date: N/A" under a dated header.
