Marc-André Bombeck 8da7583ec6 fix(auth): link single sign-on to an existing account only after its own sign-in
The SSO callback bound a verified provider email to the local account with
the same address on the spot. The local address is not verified: anyone
could register with it, or type it into their profile, and the SSO user
then landed in an account the other person still held the password to.

The callback now links nothing. It records the link it would make in a
sealed, ten-minute, HttpOnly cookie and sends the browser to the sign-in
page, and the link is made only when that browser then signs in to that
same account with its password (and second factor) or passkey. Under an
SSO-only policy the password form opens for exactly that account. The
native sign-in answers oidc_link_required; the link is confirmed once on
the web.

Moving an account to a new email address now also needs a fresh proof: a
sign-in or second factor in the last five minutes, or the current password
sent alongside the change. Without it the address is left as it was and
reported in rejectedFields; the rest of the save still lands.

Marc-André Bombeck 625763982b Narrow a spent email budget to the field, and record both refusals
A refused address change returned before the update was built, so every
other field in the same request went with it. The settings form posts
the whole profile at once, so somebody who had spent the budget could
not save a timezone or a height for an hour and was told it was about
email addresses. The address is now dropped and the rest of the save
lands, reported through the existing rejectedFields key with the code
`rate_limited`; the 429 is kept for a request that asked for nothing
else, where a partial success would be a lie.

The comment claiming an audit row beside each question was inverted:
both refusals returned before the row is written, so only the answers
that told the caller nothing were being recorded. The two answers worth
detecting write their own rows now.

The stored address is normalised before the "has it changed" comparison.
Registration writes it as typed, so an account created with capitals did
not match its own address and paid for its first ordinary save.

Marc-André Bombeck 4c858e7600 Read the height-surface guard across a split form
The onboarding step keeps the preference and the adapter where the
save happens and renders the control from its inputs file, so the
three conditions belong to the surface, not to one file. The control
check is word-bounded now: a wrapper named after it passed a substring
check while rendering something else.

Marc-André Bombeck 36cbf48286 Show a refused profile field under the input it belongs to
The onboarding baseline step flashed a toast naming one refused field
and walked on to the done screen, stamping the account as set up over
a value the server never stored. The value the person typed was gone
with the step.

A refused field now writes its reason into that field's own error
slot, marks the control invalid, and holds the step until the person
corrects it. Every refused field is named, not only the first, and the
reason comes from the validator code rather than the validator's own
prose, in all seven shipped languages.

Marc-André Bombeck 8e6880b04c Say when the onboarding profile step could not save a field
The baseline step submitted what you filled in and ignored the answer.
The profile write is field-independent: it stores everything that
validated and reports back what it declined. Nobody read that report
here, so a value the server refused vanished between the input and the
next screen and you moved on believing it was saved.

It now says which field did not make it, using the name that sits next
to the input you typed into, and keeps going with the rest that did
save. When nothing could be saved at all, the step stays put and names
the field that blocked it instead of a shrug. The wording and the
field-naming come from the same place the account form in Settings
uses, so the same refusal reads the same wherever you hit it.
