* fix: use canEditDeployGitSource for git provider access on existing deploys
Replaces the simple userId ownership check with a new canEditDeployGitSource
function that correctly handles all role/sharing scenarios. Owner always has
access; admin and member only if they own the provider or it is shared with
the org — being assigned via accessedGitProviders (enterprise) only grants
permission to connect new deploys, not to edit the git source of existing ones.
Adds 26 unit tests covering owner, admin, member (with/without enterprise
license), shared providers, and the key regression case from issue #4469.
