Modernize Beam to .NET 10 and fix dev port

[Dedac]

Summary

• upgrade Beam projects, packages, SDK tooling, and dev container to .NET 10
• improve development database connection handling with local certificate trust
• move the development server and dev-container forwarding from port 5000 to 5080 to avoid the macOS AirPlay conflict
• update startup configuration and add the devcontainer lock file

Validation

• dotnet restore Beam.Server/Beam.Server.csproj
• dotnet build Beam.Server/Beam.Server.csproj --no-restore
• verified http://localhost:5080/ returns 200 OK and serves the Blazor page

Closes #N/A

The dev-container image setup is incompatible with its new base, and VS Code debugging still defaults to port 5000.

🔵 Needs a closer look

The hard-coded workspace mount conflicts with the dynamic workspace path when the checkout directory has another name.

Keep the mounted and configured workspace paths aligned

.devcontainer/​docker-compose.yml:17

This mount target only matches workspaceFolder while the checkout directory is literally named Beam. If a contributor clones the repository under another directory name, workspaceFolder and ${containerWorkspaceFolder} resolve to /workspaces/<actual-basename>, but the source is mounted at /workspaces/Beam; VS Code then opens an unmounted path and the on-create script cannot restore the repository. Use the same fixed path in both files, or make both paths derive from one shared value.
