* fix(server): propagate --enable-proposed-api in serve-web

The `code serve-web` CLI accepts `--enable-proposed-api EXTENSION_ID`
but never propagated the allowlist to the workbench environment service
or the server-side extension scanner. As a result, extensions declaring
`enabledApiProposals` in their package.json had their proposals wiped
at runtime by ExtensionsProposedApi and failed to activate.

This wires the flag through two paths so it matches desktop behavior:

1. Server scanner: extend IProductService.extensionsEnabledWithApiProposalVersion
   in setupServerServices so the node extension scanner keeps the manifest's
   enabledApiProposals when --enable-proposed-api is passed.

2. Workbench env service: add a new `enabledExtensionProposedApi` field to
   IWorkbenchConstructionOptions, populate it from the CLI args in
   webClientServer, and surface it via BrowserWorkbenchEnvironmentService
   .extensionEnabledProposedApi so the runtime allowlist in
   ExtensionsProposedApi matches the requested IDs.

Fixes #228781

* cli: forward --enable-proposed-api to serve-web subprocess

The Rust CLI parses --enable-proposed-api as a global EditorOptions flag
but was not forwarding it to the node server subprocess spawned by
serve-web. As a result, the flag never reached the server's argv parser
and the server-side plumbing in serverServices.ts and webClientServer.ts
had no input to act on.

Capture the flag in ConnectionManager from CommandContext and pass it
through StartArgs, then append --enable-proposed-api=<id> for each
requested extension ID when spawning the server process.

* fix(server): update proposed API propagation
