Address review findings on the repo create wizard
Commit

- Shell-quote the server-derived repo address in the commands printed for recovery and next steps.
- Fix the usage line, which rendered as
create <name> [<name>]. - Keep the create response's visibility and full name when the readiness snapshot omits them, so a visibility the repo already has is not set again and the output still names the repo.
- Show the 409 conflict note only while the project it happened in is the chosen one.
- Say what the project filter does: projects reporting canCreateRepository=false are hidden, as with project create's orgs.
