GET /billing/claims loaded every tenant claim with no limit. Add
findByTenant(page, limit) + countByTenant (shared query builder), default
limit 50 / max 100, and expose totals as data.meta — kept inside the existing
{ data: { data: [...] } } envelope so current clients are unaffected.
GET /wallet/transactions was already bounded (findByUser defaulted to limit 50)
but page-less; add page/offset + countByUser + the same additive meta.
Regression: tests/Billing/ClaimsListPaginationTest,
tests/Settlement/WalletTransactionsPaginationTest.
