[feature]: Allow video attachments in ticket comments

Is there an existing issue for this?

• I have searched the existing issues

Summary

Currently, Plane does not support attaching videos directly in ticket comments.
In QA workflows, especially when failing a ticket, it is critical to attach short screen recordings to demonstrate bugs clearly.

Right now, the workaround is to upload videos to Google Drive/Dropbox and paste links in comments.
However, this is inefficient and makes tickets harder to track.

Feature Request:

• Support direct upload of video files (e.g., .mp4, .mov, .webm) in comments.

  Benefits:

• QA → Developer communication becomes faster.

• No reliance on external links.

• Easier debugging and ticket tracking.

Why should this be worked on?

Video attachments are critical for QA, product, and developer collaboration.
When reporting bugs, a short screen recording often communicates the issue far better than text or screenshots.

Without direct video uploads in comments:
• QA engineers must upload videos to external platforms (Google Drive, Dropbox, etc.).
• Developers then need to open external links, which is time-consuming and sometimes restricted by permissions.
• Over time, external links may expire, leaving tickets incomplete.

Adding direct video support will:
• Improve clarity of bug reports.
• Save time for QA and developers.
• Ensure long-term accessibility of test evidence inside Plane.
• Make Plane a more complete end-to-end issue tracking system.
