Claude f5ba646878 Address review nitpicks: model validation, scope placement, mock style, lock-safe DDL
All four checked against the repo's own conventions before applying.

Mirror the check constraint as a model validation. Assigning
reconciled_by_statement without reconciled_at raised StatementInvalid rather
than a validation error. CLAUDE.md Convention 5 asks for exactly this pairing --
the constraint in the database, an ActiveRecord validation for form-friendly
errors.

Stop hijacking the pending-scope comment. The reconciliation scopes were
inserted directly under "Pending transaction scopes", so that header read as
documentation for them and the provider note below read as a continuation of
reconciled_by. Given the reconciliation scopes their own header.

Use OpenStruct for the provider response double, per "Always prefer OpenStruct
when creating mock instances". Verified OpenStruct.new(success?: true) responds
to success?, and ostruct is already a dependency used elsewhere in test/.

Make the migration lock-safe. entries is the largest table in the app: both
indexes now build concurrently, and the check constraint is added unvalidated
then validated separately so VALIDATE takes only SHARE UPDATE EXCLUSIVE instead
of holding ACCESS EXCLUSIVE for a full scan. This follows existing practice --
13 migrations already use disable_ddl_transaction! and 11 use algorithm:
:concurrently, with add_offline_reason_to_securities combining add_column and a
concurrent index in one migration exactly like this. The suggested follow-up
migration for validation was not needed: validating in the same non-
transactional migration gets the same lock behavior without a second file, and
the repo has no validate: false precedent in 400 migrations.

schema.rb is unchanged: a validated constraint and a concurrently-built index
dump identically.
