Make ticket items in bulk update email notifications clickable

In the recent update to the Feedback Tracker email notification system, batch/bulk changes are now consolidated into a single summary email. However, the ticket entries listed inside this digest email are sent as plain text.

Users cannot click directly on the ticket titles or issue IDs (e.g., FT-106) to navigate to the ticket page, requiring manual copy-pasting of issue IDs into the browser.

Rationale / Why it's needed:

Improves Usability & Navigation: Allows users to open updated tickets directly from their email inbox with a single click.
Standard Email Practice: Digest notifications typically include hyperlinked titles or buttons for direct action/access.

Suggested Implementation:

Wrap ticket names and IDs inside the HTML template for bulk digest emails with direct hyperlinks pointing to the corresponding Feedback Tracker ticket URL ([Ticket-Id](https://report.bistudio.com/issues/Ticket-Id)...).
