DiffViewer refactor — 6-section plugin pattern + 1000-row cap. Closes task #156 (Phase 6.4 Stream C). Replaces the flat single-table rendering that mixed Namespace/DriverInstance/Equipment/Tag rows into one untyped list with a per-section-card layout that makes draft review actually scannable on non-trivial diffs. New DiffSection.razor reusable component encapsulates the per-section rendering — card header shows Title + Description + a three-badge summary (+added / −removed / ~modified plus a "no changes" grey badge when the section is empty) so operators can glance at a six-card page and see what areas of the draft actually shifted before drilling into any one table. Hard row-cap at DefaultRowCap=1000 per section lives inside the component so a pathological draft (e.g. 20k tags churned by a block rebuild) can't freeze the browser on render — excess rows are silently dropped with a yellow warning banner that surfaces "Showing the first 1000 of N rows" + a pointer to run sp_ComputeGenerationDiff directly for the full set. Body max-height: 400px + overflow-y: auto gives each section its own scroll region so one big section doesn't push the others off screen. DiffViewer.razor refactored to a static Sections table driving a single foreach that instantiates one DiffSection per known TableName. Sections listed in author-order (Namespace → DriverInstance → Equipment → Tag → UnsLine → NodeAcl) — six entries matching the task acceptance criterion. The first four correspond to what sp_ComputeGenerationDiff currently emits; the last two (UnsLine + NodeAcl) render as empty "no changes" cards today + will light up when the proc is extended (tracked in task #196 for NodeAcl; UnsLine proc extension is a natural follow-up since UnsImpactAnalyzer already tracks UNS moves). RowsFor(tableName) replaces the prior flat table — each section filters the overall DiffRow list by its TableName so the proc output format stays stable. Header-bar summary at the top of the page now reads "N rows across M of 6 sections" so operators see overall change weight at a glance before scanning. Two Razor-specific fixes landed along the way: loop variable renamed from section to sec because @section collides with the Razor section directive + trips RZ2005; helper method renamed from Group to RowsFor because the Razor generator gets confused by a parameter-flowing method whose name clashes with LINQ's Group extension (the source-gen output referenced TypeCheck<T> with no argument). Admin project builds 0 errors; Admin.Tests suite 76/76 (unchanged — the refactor is structural + no service-layer logic changed, so the existing DraftValidator + EquipmentService + AdminServicesIntegrationTests cover the consuming paths). No bUnit in this project so the cap behavior isn't unit-tested at the component level; DiffSection.OnParametersSet is small + deterministic (int counts + Take(RowCap)) + reviewed before ship.
