Fail KV workloads on final errors and wrong data

[KirillKurdyukov]

Changes

• Fail all four existing Query, JDBC, Spring Data JDBC and Spring Data JPA
  workloads on an unrecovered final logical operation error, preserving its
  SDK cause through supervision and cleanup.
• Keep one control owner with an independently retained expected generation
  and full payload. Check successful reads before advancing and after each
  acknowledged write, including during ordinary load.
• Reserve the control key outside random traffic and use a process-private
  table for the complete create/run/drop lifecycle.
• Normalize outgoing timestamps to storage precision before writing.
  Preserve existing schema, CLI, retry policies and load metrics.

Verification

• Five core tests pass and all four workload modules package with JDK17.
  The runner regression exercises stale-data detection while load is active.
• Eight original SDK source-image builds pass, without fallback images.
• Eight real ordinary processes pass across all four adapters. Concurrent
  same-label peers keep separate tables and the longer peer survives the
  shorter peer's cleanup.
• Sixteen real negative processes fail as expected: missing row, stale
  generation, wrong payload and a final SDK failure for each adapter.
  Data injection follows actual successful SDK read/decoding; SDK failures
  come from an independently dropped acknowledged private table.
• Independent source-publication gate: APPROVE, no blockers.

Both SDK roles currently use the same SDK library revision, so this is
adapter/ownership verification rather than a two-version benchmark.
Recovered successful outcomes are covered at the core seam; native forced
retry recovery and hosted SLO remain unverified.

Consumer dependency

The separate ydb-java-sdk workflow PR must pin these changed examples at
68c06dfa5f09dea42613dc5eaffb0e4c456cfd51 and enforce the process verdict.
That consumer publication/CI is a follow-up, not an unchanged-master success
claim. This PR adds neither RMW nor Topic scenarios and changes no SDK library.
