fix: Fix Teams bot crash due to Trusted Types policy

[Halo5082]

• Handle TrustedScript error when injecting browser utils
• Use Function constructor to bypass Teams Trusted Types restrictions
• Fallback to Function constructor when addScriptTag fails

[DmitriyG228]

Closing — script injection was refactored into the shared utils/injection.ts (ensureBrowserUtils), so this patch no longer applies. Teams recording now uses that util instead of addScriptTag in recording.ts. If Trusted Types issues reappear on Teams, the Function-constructor fallback can be re-implemented in injection.ts. Thanks for the contribution.
