Deactivate a ledger account

Deactivate a ledger account

Prevent new postings to an inactive account while keeping history intact.

Owner: bus accounts.

Deactivate accounts to prevent new postings to inactive targets while keeping historical postings intact. Automation should avoid selecting inactive accounts for new classification.

In the current CLI surface, deactivation is performed by setting is_active to false in accounts.csv and then running bus accounts validate (or bus validate) to ensure the result is schema-valid and consistent.
