test(operability): eliminate full-suite deprecation and transaction warnings #1116

Fresh owner reconciliation found this issue duplicated existing LineageWeave warning-repair lanes rather than defining a new product delta.

Exact hosted evidence remains useful, but ownership is now canonicalized as follows:

• OpenTelemetry LoggingHandler deprecation: observability: remove deprecated OpenTelemetry SDK LoggingHandler #1036, with existing single repair PR fix(telemetry): use supported OpenTelemetry logging handler #973. Do not duplicate or suppress it.
• PROV-O nested/imbalanced migration transaction warnings: test(prov): eliminate nested migration transaction warnings #1035, exact repair branch already carries warning-free focused/full PostgreSQL evidence pending canonical promotion gates.
• person-projection migration transaction warnings: test(postgres): align person projection migration fixture with explicit transaction ownership #1038, existing single repair PR fix(test): isolate projection migrations from seed transaction #1040 exact 4d74c32a23cdc254cf5f4d4e72804fe54aa0f1af; Tests/Security/SAST and warning-free hosted evidence are already present, canonical CodeQL/OpenCode remain pending.
• PostgreSQL Alpine locale bootstrap warnings: ci(postgres): eliminate Alpine initdb locale warning from acceptance runs #1037, existing single repair PR fix(ci): make PostgreSQL locale acceptance explicit #1039.
• the newly re-observed initdb: warning: enabling "trust" authentication for local connections has been transferred to ci(postgres): eliminate Alpine initdb locale warning from acceptance runs #1037 comment 5695341589, because it is the same PostgreSQL acceptance-fixture/bootstrap boundary; ci(postgres): eliminate Alpine initdb locale warning from acceptance runs #1037 now requires explicit supported initdb auth plus warning-free exact-head evidence before closure.

The expected database constraint-violation ERROR records in contract tests remain intentional and are not warning-cleanliness defects.

This issue has no remaining unique source/test/fixture/contract delta after that complete owner transfer, so it is closed as duplicate rather than creating competing repair lanes.
