Add the remaining 22 simple-CRUD resources

Finishes the mechanical rollout: every resource using
resource_methods!/crud_methods! in the SDK (list/get/create/update/
delete, no bulk/uploads/entity-actions) is now wired up, 33 in
total. recurring_quotes.rs mirrors recurring_invoices.rs the same
way quotes.rs mirrors invoices.rs, since RecurringQuote is also a
type alias for RecurringInvoice in the SDK.

client_gateway_tokens, companies, and system_logs use the SDK's
crud_methods! rather than resource_methods! (no /bulk route in
Invoice Ninja for these) - doesn't change anything here, since this
CLI doesn't expose bulk actions yet either way.
