fix(inject): allow user to update atomic testing with assessment capability (#5784)

[camrrx]

Proposed changes

• Allow a user assigned to a role with the Assessment capability to update an existing atomic testing.

Testing Instructions

As an Admin:

• Navigate to Settings → Security → Roles
• Create a new role with the following capabilities enabled for Assessment:
  • Access
  • Manage
  • Delete
  • Launch
• Navigate to Settings → Security → Groups
• Create a new group and assign the role created above to it
• Add a user to this group — ensure this user belongs only to this group

As the user in the newly created group:

• Navigate to Atomic Testing
• Open an existing atomic testing
• Attempt to edit it
• Observe that the inject form can be modified

Pull request overview

This PR adjusts frontend permission gating so users who have the Assessment – Manage capability can edit existing Atomic Testings (inject update form is no longer forced into read-only when the user lacks resource-grant MANAGE on the inject itself).

Changes:

• Update the inject form disabled condition to allow editing when ability.can(MANAGE, ASSESSMENT) is true (even if the user cannot manage the specific inject resource by grant).
• Keep existing protections intact (inject disabled, missing contract content, explicit permissions.readOnly, and non-NONE inherited context behavior).
