fix(project): handle registry list retrieval error gracefully in create view

## Problem
In `pkg/views/project/create/view.go`, if `getRegistryList()` fails, the entire project creation form is blocked — even though the registry selector is only needed when "Proxy Cache" is enabled. There are also unnecessary nil checks before ranging over `registries.Payload`.

## Proposed Solution
- Treat the registry list as optional: log a warning and continue if retrieval fails
- Remove unnecessary nil checks (ranging over a nil slice in Go is safe)
- Add a comment making the non-fatal intent explicit

## Affected File
- `pkg/views/project/create/view.go`

Start in pkg/views/project/create/view.go and trace how getRegistryList() is used while the project creation form is built. Confirm the registry retrieval failure path and the registries.Payload iteration. Done when retrieval failure logs a warning without blocking creation, nil checks are removed, and the non-fatal intent is documented.
