fix(translator): add 17 missing i18n keys (pipeline steps + concept diagram) (GAP-NOVO-1)

Added pipelineStepClientRequest/Desc, pipelineStepFormatDetected/Desc,
pipelineStepOpenAIIntermediate/Desc, pipelineStepProviderFormat/Desc,
pipelineStepProviderResponse/Desc, conceptDiagramArrow1-3,
conceptDiagramExampleHub, conceptDiagramHubTooltip,
conceptDiagramSourceTooltip, conceptDiagramTargetTooltip to both
en.json and pt-BR.json.

Extended translator-friendly-i18n-keys.test.ts NEW_KEYS array with all
17 new keys. Test suite now covers 69 keys (was 52) — 172 tests pass.
