ScreenTinker e5e5b75b85 Customer Entra tenants: verify the domain, then be believed
The previous fix let the instance-wide Microsoft button work and left the
customer-facing path broken, which is the worst way round. An organization that
brings its own Entra tenant would publish the TXT record, watch its domain go
green, and still be refused at login with `email_unverified` -- because Entra
sends no such claim and rowToProvider pinned the assumption off for every org
provider.

Requiring a claim Microsoft does not emit is not a security control, it is an
outage. What makes it safe to stop requiring it is the proof that already gates
these providers: the callback confines an org provider to its DNS-verified
domains, and an address only reaches the check after passing that. Whoever
controls a domain's DNS controls its mail, which is the same trust that makes a
verification link meaningful.

So the assumption is DERIVED from proof -- `verified.length > 0` -- rather than
pinned off. A provider that has verified nothing still assumes nothing, which is
belt and braces: emailAllowedForProvider already refuses it, since an empty
allow-list matches no domain, but deriving it here means a future reordering of
those checks cannot silently widen it.

It is never a column, and there is no column for it to be read from. An
organization must not be able to switch this on for itself; it is a consequence
of DNS proof, not a setting. A test asserts both -- that the value is derived
next to `source: 'org'`, and that no `assume_email_verified` exists in the
schema.

Domain confinement is untouched. An explicit `email_verified: false` is still
refused from anyone.

Mutations all fail the tests: assuming unconditionally, never assuming, and
reading it from the row.
