PR Summary — study-server

· feat: proxy global-only state estimation measurements

Proxies the state-estimation server's new endpoint to the frontend:

GET /v1/studies/{s}/root-networks/{r}/nodes/{n}/state-estimation/measurements?globalFilters=<json>

Checks the root network and node belong to the study, resolves the stored
result UUID (none → 204) + network UUID + node variant, forwards with
globalFilters encoded strictly once. filters/sort → 400. Upstream 4xx/5xx
passed through; connection failures → 502/504.

New controller endpoint, StateEstimationRestService#getStateEstimationMeasurements, StateEstimationService read path
Tests: full-HTTP encoding on both hops (tricky chars, no double-encoding), ownership/204/400/502/504, unit level

Cross-repo: upstream state-estimation server PR + downstream gridstudy-app PR

Linked PR: gridsuite/gridstudy-app#4274

Walkthrough

Adds GET /measurements for state-estimation results. The endpoint validates query parameters and study ownership, then returns measurements or no content. The service resolves the stored result and forwards the request, including optional global filters, to the state-estimation server.

Changes: Measurements retrieval

Layer / File(s)	Summary
Endpoint validation and response `src/main/java/org/gridsuite/study/server/controller/stateestimation/StateEstimationController.java`, `src/test/java/org/gridsuite/study/server/controller/stateestimation/StateEstimationControllerTest.java`, `src/test/java/org/gridsuite/study/server/StateEstimationMeasurementsEncodingTest.java`	The endpoint rejects `filters` and `sort`, verifies study ownership, and returns HTTP 200 when measurements are present or HTTP 204 when they are absent. Tests cover validation, response status, UTF-8 response bytes, downstream status propagation, and gateway failures.
Resolve state-estimation result `src/main/java/org/gridsuite/study/server/service/stateestimation/StateEstimationService.java`, `src/test/java/org/gridsuite/study/server/service/stateestimation/StateEstimationServiceTest.java`	The service returns `null` when no result UUID exists. Otherwise, it resolves the network UUID and variant ID, then requests measurements.
Downstream request and error handling `src/main/java/org/gridsuite/study/server/service/stateestimation/StateEstimationRestService.java`, `src/test/java/org/gridsuite/study/server/service/stateestimation/StateEstimationRestServiceTest.java`	The REST service builds the request with nonblank filters and variant IDs. It maps resource-access timeouts to 504 and other resource-access failures to 502. Tests cover URI encoding, omitted blank parameters, downstream errors, and connection failures.

Priority: Normal

Merge Risk: Low · up to 61ee3

A stalled state-estimation server can leave measurement requests waiting indefinitely. Configure timeouts on the shared client before merging, or explicitly accept this bounded availability risk.

Set finite connect and read timeouts on the shared RestTemplate.

RestTemplateConfig.restTemplate builds the bean with builder.build() and sets no connect or read timeout. If a downstream service accepts a connection and stops responding, this request can wait without limit. The 504 mapping for timeout exceptions then does not run for that case. The same template serves the other remote calls in this service, so the fix belongs in RestTemplateConfig, not in this endpoint.
