Add FDC3 v3 Sail demo state

[DovOps]

Summary

Adds the state 014 FDC3 v3 + Sail demo path for TraderX, based on @finos/fdc3@3.0.0-alpha.2 and the Sail v3 beta branch.

This updates the state 014 specs, generation flow, runtime scripts, and smoke tests so TraderX can run as a Sail-hosted FDC3 v3 demo with:

• TraderX-owned AppD endpoint at /fdc3/appd/v2/apps
• TraderX, Mini TraderX, and TraderX Intent Launcher supplied by TraderX AppD metadata
• compact Mini TraderX view that listens for instrument/account context and does not advertise trade/order-ticket handlers
• Sail bootstrap wired for TraderX AppD, seeded workspace expectations, and FDC3 v3 broadcast validation
• Playwright smoke coverage for Sail workspace load, TradingView panels, fdc3.instrument, and traderx.account context propagation

The local Sail override copies were removed from this state. The corresponding upstream Sail work is tracked separately so TraderX can converge on upstream Sail behavior instead of carrying patched Sail app/widget code inside the state pack.

Sail Dependency Note

State 014 is currently pinned to the Sail v3 beta line plus Dov's Sail branch work because the demo depends on three Sail improvements discovered while integrating TraderX:

• Fix workspace store persistence rehydration FDC3-Sail#314 - workspace persistence/rehydration
• Support multiple App Directory sources FDC3-Sail#315 - multiple App Directory sources
• Add frameable TradingView widget apps FDC3-Sail#316 - frameable TradingView widgets

Those Sail PRs all target finos/FDC3-Sail:sail-v3-beta. Once they land upstream, state 014 should be able to move back to the upstream Sail branch/ref instead of using the local/demo Sail branch.
