refactor: standardize project names to Musify.* and flatten layout

- Flatten nested per-repo folders into flat Musify.* projects at root - Rename assemblies/csproj: Domain->Musify.Domain, Application->Musify.Application, Infrastructure->Musify.Infrastructure, WebApi->Musify.Api, Worker->Musify.Worker, StreamingGateway->Musify.StreamingGateway - Rename WebApi.* namespaces to Musify.Api.* - Update all ProjectReference paths and the solution file - Consolidate stray per-repo dotfiles; add root .gitattributes - Move flutter client out to _archive
