A call to gnubok_categorize_transaction carrying only account_override reached
the enum check in categorizeTransactionCore and surfaced as
'Invalid category "undefined"'. Hosts do not always enforce inputSchema
`required`, so the executor now guards presence at the boundary and throws
"category is required; account_override only overrides the category's default
account" (listing the valid categories). Unknown category strings still get
the existing enum error.
Same class in gnubok_bulk_book_inbox_items: a missing or unknown category was
staged as-is and only rejected at approval time by the commit executor's Zod
schema. It now fails at staging with the same clear messages.
The account_override property description spells out that category stays
required (it decides direction and VAT) and the override only replaces its
default account.
Closes#1662
