URI truncated at ~80 chars despite available space (UI issue)

**Describe the bug**
URI field is front-truncated (`...`) in the UI, although the full value exists and there is sufficient space in the layout.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://identifier.buildingsmart.org/uri/buildingsmart/ifc/4.3/class/IfcBuilding
2. Locate the Identifier (URI) field
3. Observe truncated display:
`.../uri/buildingsmart/ifc/4.3/class/IfcBuilding`

**Expected behavior**
The full URI should be visible and recognizable as a URI (e.g. including `https://`), ideally as a clickable link.

**Desktop (please complete the following information):**
- OS: macOS
- Browser: Chrome
- Version: 146.0.7680.80

**Additional context**
- 76 chars (OK):
https://identifier.buildingsmart.org/uri/buildingsmart/ifc/4.3/class/IfcWall
- 80 chars (truncated display vs full):
.../uri/buildingsmart/ifc/4.3/class/IfcBuilding
https://identifier.buildingsmart.org/uri/buildingsmart/ifc/4.3/class/IfcBuilding

Hard cutoff at ~80 chars. A copy button provides the full URI, but truncation is unnecessary and reduces readability.
Front-truncation also hides the URI prefix, making it less obvious that this is a resolvable linked data identifier.
