refactor: enforce company restrictions on any doctype with a Company link

Replace the manually maintained transaction allowlist with a wildcard
validate hook: any doctype carrying a Company link field is checked, so
new doctypes are covered automatically. System-managed doctypes (ledger
entries, reposts, bundles, bins, POS consolidation, bank feeds) are
exempted so cancel, repost and reconciliation of documents created
before a restriction changed keep working; that guarantee is pinned by
a cancel-after-restriction test.
