[CLI] Portal Extensions microservice client support

[gabrielbeamable]

Summary

• Fix portal extension dependency management to read/write microserviceDependencies under the beamable key in package.json instead of at the root level
• Generate TypeScript clients (.ts) instead of JavaScript (.js) and fix SDK import paths to use @beamable/sdk instead of beamable-sdk
• Handle content manifest 404 as an empty manifest in the Web SDK, fixing errors on realms with no published content
• Change RequestPortalExtensionData from [ClientCallable] to [Callable] to remove the requirement for an initialized player
• Fix dev-web.sh to publish with --tag local to avoid polluting the latest npm tag

Changes

Portal Extension dependency & client generation (cli/)

• PortalExtensionAddDependencyCommand.cs: Dependencies are now read/written under package.json > beamable > microserviceDependencies instead of the root. Added validation that the beamable field exists. Split the skip condition for missing dependencies vs missing OpenAPI doc, with a warning log when the doc
  isn't available. Client code is now generated as .ts files.
• PortalExtensionConstants.cs: Added EXTENSION_BEAMABLE_PROPERTY_NAME constant for the new beamable key.
• WebClientCodeGenerator.cs: Fixed import paths from beamable-sdk and beamable-sdk/schema to @beamable/sdk and @beamable/sdk/schema.
• React template tsconfig.json: Added beamable/**/*.ts to include so generated client types are picked up.

Portal Extension discovery (PortalExtensionDiscoveryService.cs)

• Changed [ClientCallable] to [Callable] so portal extensions can be served without requiring a fully initialized player session.

Web SDK content service (ContentService.ts)

• Wrapped manifest checksum fetch in try/catch to handle 404 responses gracefully — treats them as an empty manifest instead of crashing. Added isManifestNotFound helper.

Dev tooling (dev-web.sh)

• Added --tag local to pnpm publish commands to prevent local dev builds from overwriting the latest tag in the local registry.

Test plan

• Run beam pe add-dep on a portal extension with a microservice dependency — verify package.json is updated under beamable.microserviceDependencies and a .ts client is generated with correct @beamable/sdk imports
• Load a portal extension in the portal without being logged in as a player — verify it loads (no ClientCallable auth requirement)
• Open a realm with no published content — verify no crash and content page shows empty state
• Run dev-web.sh — verify packages are published with --tag local in the local registry
