feat(analytics): add source field to creation and execution events [INS-2427]

[pavkout]

Summary

• Adds a source property to analytics creation and execution events to
  differentiate where users trigger actions from (home page, sidebar, navbar, etc.)
• Covers: Request Created, Request Executed, Collection Created, Document Created,
  Mock Created, MCP Client Workspace Created, and Environment Created
• Import Started already had source on all call sites — no change needed

Analytics Events

requestExecuted — added source property

Source	Trigger
request-pane	Send button in the request pane

environmentCreate — added source property

Source	Trigger
environment-editor	"Add environment" in the environment editor route
environment-editor	"Add environment" in the workspace environments modal

workspaceCreate — added source property (all scopes: collection, design, environment, mcp, mock-server)

Source	Trigger
navbar	Top-bar "New" dropdown on the project home page
empty-state	Empty state card on the project home page (design doc only)
home-page	First request creation button on the project home page
sidebar-dropdown	Project context menu in the sidebar
sidebar	Empty-node actions inside the sidebar navigation tree
design-view	"Create mock server" button in the API spec/design tab (mock-server only)

requestCreated — new event

Fired when a collection is created together with a first HTTP request.

Source	Trigger
home-page	Create collection with first request on the project home page

mockCreate — source now dynamic

Previously hardcoded as menu. Now inherits the same source values as workspaceCreate (navbar, sidebar-dropdown, sidebar, design-view). Omitted entirely when no source is provided.

Pull request overview

Adds a source attribute to multiple analytics “creation” and “execution” events so product analytics can distinguish where actions were triggered from (home page, navbar, sidebar, tab bar, etc.).

Changes:

• Thread a source string through request/workspace/environment creation flows and attach it to corresponding analytics events.
• Add source attribution for request execution (“Request Executed”) from the request pane.
• Plumb source through dashboard → NewWorkspaceModal → workspace/new route, and through request/environment fetcher submit hooks.
