* fix(mcp): query_journal accepts scalar/number accounts instead of silently dropping the filter
Hosts don't always enforce inputSchema. `accounts: 1630` (JSON number) has no
`.length`, so the account filter was skipped while applied_filters still
echoed it, returning every account's lines as if filtered. A bare string
"1630" was spread into its digits by postgrest-js `.in()` and matched nothing.
Normalize accounts (array / bare string / comma list / integer) to string[]
and account_from/account_to to strings; reject values that aren't account
numbers with a clear error instead of ignoring them. Tests assert the actual
`.in('account_number', [...])` predicate, not just the echo.

* fix(mcp): reuse shared ACCOUNT_NUMBER_RE, drop null entries, normalize tag_journal_lines filters
Review fixes: the local ACCOUNT_NUMBER_RE collided with the import from
lib/invariants/account-number (build break); null/undefined array entries
now drop out instead of reaching .in(); gnubok_tag_journal_lines (a bulk
write path) gets the same accounts/account_from/account_to normalization so
a mangled filter fails fast instead of widening the retag scope.
