Reinforce documentation for 32 remaining modules (90–95% API coverage, EN+RU)

[dsudomoin]

Summary

Reinforces the documentation for the 32 modules not yet covered, bringing each to 90–95% coverage of its public API, verified against the actual Kora sources (branch 1.0 = release 1.2.17). English is written/expanded first, then Russian is re-translated to keep strict EN/RU parity. Follows the existing http-server / http-client / kafka reinforcement pattern.

What changed — 4 commits, 64 files (EN+RU)

• grpc-server, grpc-client, database-jdbc, database-r2dbc, config, container
• json, validation, cache, resilient, scheduling, metrics, tracing, s3-client, openapi-codegen, mapstruct
• database-cassandra, database-common, database-migration, general, junit5, logging-aspect, logging-slf4j, netty, openapi-management, probes
• camunda7-bpmn, camunda7-rest, camunda8-worker, database-vertx, graalvm-native, soap-client

Plus .gitignore: ignore .kora-agent/ (local Kora sources cloned for verification) and .DS_Store.

How it was verified

Each module went through: gap analysis → write EN → independently verify that every documented class / interface / annotation / method / config key exists in the cloned Kora sources → correct or remove anything that doesn't → translate to RU → final QA.

The source-verification step corrected real inaccuracies before they shipped, e.g.:

• tracing: exporter.retry → retryPolicy; TracingModule → OpentelemetryTracingModule
• container: All<T> shown as sealed … permits AllImpl
• soap-client: marshalling exceptions extend RuntimeException (not SoapException)
• s3-client: @Bucket array syntax; corrected the testing link to junit5.md
• removed hallucinated identifiers from a few frontmatter trigger lists (junit5, probes, logging-slf4j, database-vertx, camunda7-bpmn)

Structural invariants checked across all modules: EN/RU heading & anchor parity, paired Java/Kotlin tabs, balanced code fences, no Cyrillic in EN prose, all in-page and cross-file links resolve.

Note: mkdocs build --strict was not run (mkdocs not available in the authoring environment); links/anchors/tabs were validated by hand. A --strict build in CI is recommended as a final check.

Style

Follows the reinforced reference docs: Java+Kotlin tabs for every API, (required, no default) / (default: value) config style, Description + Causes + Recommendations for exceptions, no ???+ tip blocks. All API claims are backed by Kora 1.0 (1.2.17) sources.
