Refactor installer scripts and update components

Renamed afterInstall.ps1 to postInstall.ps1 and added telemetry support for PostHog. Updated Python embeddable package URLs to version 3.14.0. Revised setup.iss to improve component granularity, update author info, and integrate the new post-install script and telemetry parameters.
