Update config for local dev; add AyCode.Blazor consumers doc

- Added AyCode.Blazor/CONSUMERS.md to document consumer repos and usage for impact assessment.
- Switched appsettings.json URLs to localhost for local development; production URLs are now commented out.
- Commented out Blazor/DevExpress compression and optimization settings in .csproj files.
- Minor whitespace and indentation cleanups.
- No functional code changes.

+# AyCode.Blazor — Consumer Workspace Map
+
+> **Bounded consumer-awareness exception** to the Framework-First Design Principle (LLMP-DEC-62): this single file lists which higher-layer repos consume `AyCode.Blazor` (Layer 1 UI framework). For change-impact assessment when modifying ACBLAZOR — NOT a coupling vector.
+>
+> **Strict rule**: AyCode.Blazor code, types, namespaces, topic IDs, and any other `.md` files MUST NOT name any specific consumer listed here. **This is the SINGLE place** in ACBLAZOR that may name consumer repos.
+
+## Workspace consumer map (as of 2026-07-08)
+
+| Prefix     | Repo               | Layer | Type            | Path (workspace-relative)     | Brief usage                                                              |
+|------------|--------------------|------:|-----------------|-------------------------------|---------------------------------------------------------------------------|
+| `FBANKAPP` | FruitBankHybridApp |     2 | product (hybrid)| `Mango/Source/FruitBankHybridApp` | MAUI/Blazor hybrid client — MgGrid + SignalR datasource stack            |
+| `GIAAPP`   | GiaApp             |     2 | product (web)   | `Mango/Source/GiaApp`         | Blazor Server app — MgGrid with server-side data (no SignalR datasource)  |
+
+(See `AyCode.Core/.github/REPO_PREFIXES.md` for the prefix scheme; each consumer's own `.github/copilot-instructions.md` `@repo` block declares its `prefix` value.)
+
+## When modifying AyCode.Blazor — change-impact lens
+
+- A breaking change to `MgGridBase` / `MgGridWithInfoPanel` affects both consumers above.
+- A change to `MgGridSignalRDataSource` affects only SignalR-datasource consumers (FBANKAPP; GIAAPP binds server-side data directly).
+- DevExpress version bumps cascade to every consumer (license + API compatibility check per consumer).
+
+**Do NOT** use this list to write framework code that conditionalizes on specific consumers. Generic abstractions only. The list is a **HEURISTIC for impact**, not an **INPUT to logic**.
+
+## Maintenance
+
+When a repo joins or leaves the workspace consuming AyCode.Blazor, update the table above. The list ITSELF is workspace-meta-tooling — not framework code domain.
