Add IsHidden field to Repository model. Three visibility modes:
- Public: visible to everyone (green label)
- Private: members only, non-members see 403 Access Denied (orange)
- Hidden: members only, non-members see 404 Not Found (red)
Private mode is for commercial repos — customers know the repo
exists and see a styled 403 page with sign-in button. Licensed
update feeds and key-gated downloads still work.
Hidden mode is for internal/secret repos — complete stealth, as
if the repo doesn't exist.
Settings UI: radio button selector in danger zone replaces the
old binary toggle. Each option shows a colored label with
description.
Migration v342: adds is_hidden column to repository table.
