Add GET /openmeter/customers/{customerId}/entitlements/{entitlementId}
(get-customer-entitlement) and GET /openmeter/customers/{customerId}/entitlements
(list-customer-entitlements) mirroring the v2 customer entitlement reads.
The list follows the v3 AIP conventions: page-based pagination, `sort` on
created_at/updated_at, and exact-match filters on feature_id, feature_key and
type. Only entitlements active at request time are returned. Both operations
resolve the customer through the entitlement service facade, so a deleted
customer fails with 412 and a missing customer or entitlement with 404; an
entitlement owned by another customer is also reported as not found.
refactor: use filter types in adapter layer
refactor: move sort validator into the service layer

- Around line 153-166: Update the entitlement type validation around
ListCustomerEntitlementsInput.Type to inspect every string-valued FilterString
operator, including Nin, Like, Nlike, Ilike, Nilike, Contains, Ncontains, Gt,
Gte, Lt, and Lte, while preserving existing validation for Eq, Ne, and In/Oeq.
Recursively validate values inside nested And and Or filters so unknown
entitlement types cannot reach filter.ApplyToQuery.

Validate every string-valued filter.FilterString operator. ListCustomerEntitlementsInput.Type reaches filter.ApplyToQuery, so Nin, Like, Nlike, Ilike, Nilike, Contains, Ncontains, Gt, Gte, Lt, and Lte can carry unknown values past this loop. And and Or can also hide these values in nested filters. The HTTP filter[type] shape accepts only Eq, Neq, and Oeq; Oeq maps to In and is already covered. Validate all string-valued operators, including nested filters, rather than adding only Nin.

Overview
Stacked on #5152. Adds the v3 read counterparts of the legacy
getCustomerEntitlementV2/listCustomerEntitlementsV2operations:GET /openmeter/customers/{customerId}/entitlements/{entitlementId}—get-customer-entitlement. Path params are ULIDs (no id-or-key resolution). Returns theBillingEntitlementunion.GET /openmeter/customers/{customerId}/entitlements—list-customer-entitlements. Page-based pagination (page[number],page[size], default 1/20),sortoncreated_at(default, asc) orupdated_at, and exact-match filtersfilter[feature_id](ULIDFieldFilter),filter[feature_key]andfilter[type](StringFieldFilterExact). Only entitlements active at request time are returned, mirroring v2.Both operations go through the existing
CustomerEntitlementAPIServicefacade (GetCustomerEntitlementInput,ListCustomerEntitlementsInputwithValidate()), reusinggetActiveCustomer: a deleted customer fails with 412, a missing customer or entitlement with 404. An entitlement owned by a different customer is also reported as 404 so it is not revealed through another customer's path.Also wires the routes in
api/v3/server, regenerates the OpenAPI/TS/Go SDK outputs, and adds unit tests (input validation, filter/sort converters), a PostgreSQL-backed service test, a route registration case, and an e2e test.Notes for reviewer
neqon any of them returns 400 rather than being silently ignored.oeqvalues are deduplicated.ListEntitlementsParamsalready supports (created_at,updated_at); noidtie-breaker is added, same as v2.ActiveAt = now+IncludeDeletedAfter = now, i.e. the same semantics as v2listCustomerEntitlementsV2; there is noinclude_deletedtoggle.TestV3GetAndListCustomerEntitlementshas not been executed against a live server.Summary by CodeRabbit

The PR appears safe to merge; no outstanding findings or new failures remain in the changes since the previous review.
Summary
Adds v3 customer entitlement read endpoints and corresponding generated SDK support.
