Document Link be dedicated

Problem Description:

There is a critical bug in the way the system handles links when a new version of a document is created. The linking behavior is inverted, causing links to point to the wrong versions and breaking the ability to reference specific historical versions.

Steps to Reproduce:

Upload a document, which becomes Version 1.

Generate a link for Version 1.

Let's call this Link_A.

Create a new version of the document, which becomes Version 2.

Observe the behavior of the links.

Expected Behavior:

Link_A should remain a permanent link that always points to Version 1.

Generating a new link for Version 2 should create a separate link (Link_B) that points exclusively to Version 2.

Actual (Incorrect) Behavior:

The system appears to do the opposite. The original Link_A (which should point to Version 1) is now reused and points to the new Version 2. Furthermore, if you try to generate a link for the old Version 1, the system generates a new link that incorrectly points to Version 2. It has become impossible to get a direct, stable link to Version 1. Impact: This bug makes it impossible to share reliable links to specific document versions, which is a critical requirement for audit trails, quality control, and collaborative reviews. It creates a high risk of users accessing and working with the wrong information.
