feat: Add optional raster logo to software platforms

Platforms (Xbox, PlayStation, PC, etc.) were displayed as plain text/chips with no visual identity. This adds a single optional logo per platform, shown as a small icon next to the platform name. Unlike CompanyLogo (which supports multiple SVG logos per company, versioned by year, for rebrand history), platforms only need one raster logo with no history, so this introduces a simpler, separate model: LogoId (Guid?) and LogoExtension (string?) stored directly on SoftwarePlatform rather than a new child entity. Backend: - SoftwarePlatform gains nullable LogoId/LogoExtension columns (migration AddSoftwarePlatformLogo). - New POST/DELETE /software/platforms/{id}/logo endpoints (Admin only). Upload accepts JPEG/PNG/WebP/BMP up to 5MB, validated by extension and content type. Reuses the existing ImageMagick-CLI-backed Photos helper (same one used for screenshots/photos) to convert the upload into JPEG/WebP/AVIF variants under assets/photos/platform-logos/, sized for an icon (256px full / 64px thumb) rather than the 4K/512px tiers used for photos. Replacing or deleting a logo cleans up all rendered files. - SoftwarePlatformDto exposes logo_id/logo_extension; GET list/single projections include them. Platform cache is invalidated on logo upload/delete same as other mutations. - Photos.EnsureCreated for "platform-logos" registered at startup. Web UI (legacy Blazor): - SoftwarePlatformDialog (admin edit dialog) gets an upload/preview/ remove logo control, calling the new endpoints directly since there's only one logo to manage (no separate logo-list page needed). - Platform chips on the /software landing page and the admin platforms grid show a small thumbnail next to the name when a logo is set. Uno app (Marechai.App): - AdminSoftwarePlatformsViewModel/Page get the same upload/remove logo capability in the edit panel, using FileOpenPicker and the regenerated Kiota client. New localized strings (LogoLabel, UploadLogoButton, RemoveLogoButton, FailedToUploadLogo, FailedToRemoveLogo) added across all 5 languages (en/de/es/fr/pt-BR). API client: - openapi.yaml and Marechai.ApiClient regenerated from a running server instance to pick up the new endpoints and DTO fields (LogoRequestBuilder, extended SoftwarePlatformDto). Diff is purely additive.
