ensureDbCompatibility ran ALTER TABLE / CREATE TABLE IF NOT EXISTS on the
login, register, token and session paths, mirroring columns every
migration under prisma/migrations already creates. The entrypoint applies
those migrations before the server listens and stops the boot when one
fails, so the mirror never had work to do, and DDL on a request path
needs the table's owner: a connection that may only read and write rows
fails every login on it. Drop the module, its call sites and the mocks
that stubbed it out.
A workout logged by hand could only be deleted and logged again. The
detail page now offers an edit control beside delete for a MANUAL workout
carrying the form's `manual:` id, in one's own record. It opens the log
sheet on the stored values and saves by re-posting that id through
`POST /api/workouts/batch`, which already applies such a re-post as an
overwrite of that one row. No new route.
The overwrite nulls every overwritable column a re-post leaves out, and
the form has no fields for heart rate, steps, elevation or pauses. The
edit therefore sends those back as stored. A field left as shown sends the
stored value rather than one re-parsed from its display, so saving an
untouched edit keeps the start's seconds and a distance shown in miles at
its exact metres, and answers `duplicate`.
The detail read's `avgHr` / `maxHr` can come from a same-session twin;
the read now also serves the row's own `storedAvgHr` / `storedMaxHr`,
which is what the edit sends back.
