fix(auth): en afvist passkey sagde "forkert e-mail eller adgangskode"

Der er hverken en e-mail eller en adgangskode i et passkey-login. Loginet er
discoverable — enheden ved selv, hvilken konto nøglen hører til, og der bliver
ikke tastet noget. Alligevel fik en afvisning fladens generiske 401-tekst, og den
nævner begge dele.

Det sendte en person ud at lede efter en tastefejl i sin konto, der aldrig havde
været der. Det, der faktisk var sket, var at instansen var flyttet fra http til
https: en passkey hører til præcis den adresse, den blev lavet på — `RPOrigins`
bygges af `VERDANDE_BASE_URL` med skema og alt — så et login på det ene skema mod
en server, der venter det andet, kan ikke verificeres.

Beskeden siger nu det, og siger også hvor man skal kigge. Serveren har hele tiden
svaret "that key was not accepted"; det var oversættelsen i fladen, der gjorde
den til noget andet.

Aflysning bliver behandlet som før — den er ikke en fejl, og en fejl for den ville
læse som om nøglen blev afvist.

+-- One row per person *and scope*, which is what the table always meant.
+--
+-- `user_settings` was created with `user_id` as its whole primary key, and its
+-- upsert rewrote `scope` on conflict. So a person had exactly one settings row,
+-- and whichever scope was written last was the only one that survived: saving an
+-- AI provider deleted the Gmail connection, and connecting a calendar deleted the
+-- AI provider. Nothing reported it — the write succeeded, and the loss was in the
+-- row it landed on.
+--
+-- This was seen coming twice. Migration 0011 gave the instance's settings their
+-- own table partly for this reason and wrote the warning down in as many words;
+-- 0014 moved mailboxes out and said the warning "was nearly walked into a second
+-- time". The third time was the calendar, which added a `calendar` scope beside
+-- `ai` and `gmail` — and walked in.
+--
+-- The lesson worth keeping: a warning in a migration is read by whoever is editing
+-- *that* migration, and nobody was. The shape is fixed here so there is nothing
+-- left to warn about.
+--
+-- SQLite cannot change a primary key in place, so the table is rebuilt. Existing
+-- rows are copied as they are: each person has at most one, and it holds whatever
+-- scope won last. What the earlier writes lost is already gone and cannot be
+-- recovered here — the values were overwritten, not orphaned.
