Dedicated video viewer route for reported issues

[adithya1012]

Description

When a GitHub issue is created, the link inside the ticket should point to a PulseVault page that renders the video — not a raw zip download. Knowing the URL should not be enough to access the content; a valid API token with download privilege is required.

Tasks

• Add a new route GET /view/:issueId that serves a styled player page for the uploaded video
• Gate access behind a valid API token with at minimum the download privilege
• The GitHub issue body should embed this URL, not a direct link to the zip file
• Do not show the raw storage path/UUID in the UI
