Problem:
In HashiCorp Vault, the description of an existing secrets engine cannot be changed in place. The description is set only at mount time. There is no command or API to update the description field of an already-mounted secrets engine.
If changing the description is important, i must remount the engine and will loose all secrets data.

Requested improvement:

• Allow updating the secrets engine description after creation (editable field)
• Display the description consistently in the Vault UI (e.g., in the secrets list and engine details view)

This would improve usability and reduce the need for disruptive remounts solely to update metadata.
