BernhardBuckel 52ea3b9c2f feat(labs): link a marker to its analyte for the unit conversion ...

Slice 1 of phase 3 of #1095. A Biomarker row keeps only its name, so nothing
said which analyte it was. This adds the explicit alias list in the catalog the
issue settled on, including the registry-only keys (urea, blood urea nitrogen,
uric acid, total calcium, total bilirubin), and sets biomarkers.analyte_key
(from migration 0385) from it.

matchAnalyteKey equals a marker's folded name against the localised names of the
catalog seeds the registry knows and against the alias list. It matches the
whole name only, so "Calcium (ionisiert)" is not "Calcium"; a name two analytes
claim matches neither; and the marker's own unit must be one the analyte reaches,
so a marker called "Glucose" in a unit the registry cannot convert stays
unlinked.

The key is set when a marker is created (the biomarker route, the mint used by
lab writes, the legacy backfill) and, for an existing marker, by
ensureAnalyteKey the first time a reading needs it. It never overwrites a key
that is set. There is no boot job for the existing markers: the conversion that
uses the key fills it on first use, and a sweep can be added later if wanted.

The key is returned on the biomarker API and in the OpenAPI schema.
